The TPA6203A1 does not require input coupling The TPA6203A1 is a high-performance CMOS audiocapacitors if using a differential input source that is amplifier that requires adequate power supplybiased from 0.5 V to VDD - 0.8 V. Use 1% tolerance decoupling to ensure the output total harmonicor better gain-setting resistors if not using input distortion (THD) is as low as possible. Power supplycoupling capacitors. decoupling also prevents oscillations for long lead

lengths between the amplifier and the speaker. ForIn the single-ended input application an input higher frequency transients, spikes, or digital hash oncapacitor, CI, is required to allow the amplifier to bias the line, a good low equivalent-series- resistancethe input signal to the proper dc level. In this case, CI (ESR) ceramic capacitor, typically 0.1 µF to 1 µF,and RI form a high-pass filter with the corner placed as close as possible to the device VDD leadfrequency determined in Equation 2. works best. For filtering lower frequency noisesignals, a 10-µF or greater capacitor placed near theaudio power amplifier also helps, but is not requiredin most applications because of the high PSRR of thisdevice.

Low-ESR capacitors are recommended throughoutthis applications section. A real (as opposed to ideal)capacitor can be modeled simply as a resistor inseries with an ideal capacitor. The voltage dropacross this resistor minimizes the beneficial effects ofthe capacitor in the circuit. The lower the equivalentvalue of this resistance the more the real capacitorbehaves like an ideal capacitor.

The value of CI is important to consider as it directlyaffects the bass (low frequency) performance of the SINGLE-ENDED OUTPUTcircuit. Consider the example where RI is 10 kΩ and

Equation 2 is reconfigured as Equation 3.TPA6203A1 amplifier has differential outputs drivingboth ends of the load. There are several potentialbenefits to this differential drive configuration, butinitially consider power to the load.

Plugging 2 × VO(PP) into the power equation, whereThis leakage current creates a dc offset voltage at the voltage is squared, yields 4× the output power frominput to the amplifier that reduces useful headroom, the same supply rail and load impedance (seeespecially in high gain applications. For this reason, a Equation 4).ceramic capacitor is the best choice. When polarized

capacitors are used, the positive side of the capacitorshould face the amplifier input in most applications,as the dc level there is held at VDD/2, which is likelyhigher than the source dc level. It is important toconfirm the capacitor polarity in the application.

For example, a 68-µF capacitor with an 8-Ω speakerwould attenuate low frequencies below 293 Hz. TheBTL configuration cancels the dc offsets, whicheliminates the need for the blocking capacitors.Low-frequency performance is then limited only bythe input network and speaker response. Cost andPCB space are also minimized by eliminating thebulky coupling capacitor.

In a typical wireless handset operating at 3.6 V,bridging raises the power into an 8-Ω speaker from asingled-ended (SE, ground reference) limit of 200mW to 800 mW. In sound power that is a 6-dBimprovement—which is loudness that can be heard.In addition to increased power there are frequencyresponse concerns.

EFFICIENCY AND THERMAL INFORMATIONClass-AB amplifiers are inefficient. The primary causeof these inefficiencies is voltage drop across theoutput stage transistors. There are two componentsof the internal voltage drop. One is the headroom ordc voltage drop that varies inversely to output power.The second component is due to the sinewave natureof the output. The total voltage drop can becalculated by subtracting the RMS value of the outputvoltage from VDD. The internal voltage drop multipliedby the average value of the supply current, IDD(avg),determines the internal power dissipation of theamplifier. Figure 33. Voltage and Current Waveforms for

BTL AmplifiersAn easy-to-use equation to calculate efficiency startsout as being equal to the ratio of power from thepower supply to the power delivered to the load. To Although the voltages and currents for SE and BTLaccurately calculate the RMS and average values of are sinusoidal in the load, currents from the supplypower in the load and in the amplifier, the current and are very different between SE and BTLvoltage waveform shapes must first be understood configurations. In an SE application the current(see Figure 33). waveform is a half-wave rectified shape, whereas in

BTL it is a full-wave rectified waveform. This meansRMS conversion factors are different. Keep in mindthat for most of the waveform both the push and pulltransistors are not on at the same time, whichsupports the fact that each amplifier in the BTLdevice only draws current from the supply for half thewaveform. The following equations are the basis forcalculating amplifier efficiency.

TI is not responsible or liable for any such statements.Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designersremain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers havefull and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI productsused in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, withrespect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerousconsequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm andtake appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer willthoroughly test such applications and the functionality of such TI products as used in such applications.TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information,including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended toassist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in anyway, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resourcesolely for this purpose and subject to the terms of this Notice.TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TIproducts, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections,enhancements, improvements and other changes to its TI Resources.

Using products in an application does not by itself establish any safety features in the application. Designers mustensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products inlife-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use.Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., lifesupport, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, allmedical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S.TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product).Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applicationsand that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatoryrequirements in connection with such selection.Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer’s non-compliance with the terms and provisions of this Notice.
