LT1102I

High Speed, Precision, JFET Input Instrumentation Amplifier (Fixed Gain = 10 or 100)

Linear Technology 

ELECTRICAL CHARACTERISTICS

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability 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 1GΩ

swamps the contribution of current noise.

Note 4: This parameter is not tested. It is guaranteed by design and by

inference from the slew rate measurement.

Note 5: Overdrive recovery is defined as the time delay from the removal

of an input overdrive to the output’s return from saturation to linear

operation.

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 by

inference from other tests.
