    OPA1612-Q1 SoundPlus High-Performance, Bipolar-Input Audio Operational Amplifier 1 Features 3 Description

    The OPA1612-Q1 device is a dual, SoundPlus™, 1• Qualified for Automotive Applications

    bipolar-input operational amplifierthat achieves• AEC-Q100 Qualified With the Following Results: achieve very low 1.1-nV/√Hz noise density with an – Device Temperature Grade 1: –40°C to ultralow distortion of 0.000015% at 1 kHz. The

    +125°C Ambient Operating Temperature OPA1612-Q1 device offers rail-to-rail output swing to within 600 mV with a 2-kΩ load, which increasesRange headroom and maximizes dynamic range. These– Device HBM Classification Level 2 devices also have a high output drive capability of

    – Device CDM Classification Level C6 ±30 mA. • Superior Sound Quality These devices operate over a very wide supply range • Ultralow Noise: 1.1 nV/√Hz at 1 kHz of ±2.25 V to ±18 V, on only 3.6 mA of supply current

    per channel. The OPA1612-Q1 op amp is unity-gain• Ultralow Distortion: stable and provide excellent dynamic behavior over a0.000015% at 1 kHz wide range of load conditions.• High Slew Rate: 27 V/μs The dual version features completely independent• Wide Bandwidth: 40 MHz (G = +1) circuitry for lowest crosstalk and freedom from• High Open-Loop Gain: 130 dB interactions between channels, even when overdriven

    • Unity Gain Stable or overloaded. • Low Quiescent Current: The OPA1612-Q1 device is available in a SOIC-83.6 mA per Channel package. The device is specified from –40°C to • Rail-to-Rail Output +125°C. • Wide Supply Range: ±2.25 V to ±18 V
