– Drift with Temperature: 2μV/°C■ Input Bias Current: 40pA Max■ Input Offset Current: 40pA Max

– Drift with Temperature (to 70°C): 0.5pA/°C

The LT®1102 is the first fast FET input instrumentationamplifier offered in the low cost, space saving 8-pinpackages. Fixed gains of 10 and 100 are provided withexcellent gain accuracy (0.01%) and non-linearity (3ppm).No external gain setting resistor is required.

Slew rate, settling time, gain-bandwidth product,overdrive recovery time are all improved compared tocompetitive high speed instrumentation amplifiers.

Industry best speed performance is combined withimpressive precision specifications: less than 10pA inputbias and offset currents, 180μV offset voltage. Unlikeother FET input instrumentation amplifiers, on the LT1102there is no output offset voltage contribution to total error,and input bias currents do not double with every 10°C risein temperature. Indeed, at 70°C ambient temperature theinput bias current is only 40pA.

ELECTRICAL CHARACTERISTICSNote 1: Stresses beyond those listed under Absolute Maximum Ratingsmay cause permanent damage to the device. Exposure to any AbsoluteMaximum Rating condition for extended periods may affect devicereliability and lifetime.Note 2: This parameter is tested on a sample basis only.Note 3: Current noise is calculated from the formula:in = (2qIB)1/2

where q = 1.6 • 10–19 coulomb. The noise of source resistors up to 1GΩswamps the contribution of current noise.

Note 4: This parameter is not tested. It is guaranteed by design and byinference from the slew rate measurement.Note 5: Overdrive recovery is defined as the time delay from the removalof an input overdrive to the output’s return from saturation to linearoperation.50% overdrive equals VIN = ±2V (G = 10) or VIN = ±200mV (G = 100).Note 6: This parameter is not tested. It is guaranteed by design and byinference from other tests.

In the two op amp instrumentation amplifier configura-tion, the first amplifier is basically in unity gain, and thesecond amplifier provides all the voltage gain. In theLT1102, the second amplifier is decompensated for gainof 10 stability, therefore high slew rate and bandwidth areachieved. Common mode rejection versus frequencyis also optimized in the G = 10 mode, because thebandwidths of the two op amps are similar. When G = 100,this statement is no longer true; however, by connectingan 18pF capacitor between pins 1 and 2, a common modeAC gain is created to cancel the inherent roll-off. From200Hz to 30kHz, CMRR versus frequency is improved byan order of magnitude.

Input Protection

Instrumentation amplifiers are often used in harshenvironments where overload conditions can occur.The LT1102 employs FET input transistors, consequentlythe differential input voltage can be ±30V (with ±15Vsupplies, ±36V with ±18V supplies). Some competitiveinstrumentation amplifiers have NPN inputs which areprotected by back-to-back diodes. When the differentialinput Voltage exceeds ±13V on these competitive devices,input current increases to milliampere level; more than±10V differential voltage can cause permanent damage.

When the LT1102 inputs are pulled below the negativesupply or above the positive supply, the inputs will clampa diode voltage below or above the supplies. No damagewill occur if the input current is limited to 20mA.

Common Mode Rejection Ratiovs Frequency

Gains Between 10 and 100

Gains between 10 and 100 can be achieved by connectingtwo equal resistors (= RX) between pins 1 and 2 and pins7 and 8.

The nominal value of R is 1.84kΩ. The usefulness of thismethod is limited by the fact that R is not controlled tobetter than ±10% absolute accuracy in production.However, on any specific unit, 90R can be measuredbetween Pins 1 and 2.
