INA121 - Burr-Brown Corporation

INA121 FET-Input/ Low Power INSTRUMENTATION AMPLIFIER

The INA121 is a FET-input, low power instrumentation amplifier offering excellent accuracy. Its versatile three-op amp design and very small size make it ideal for a variety of general purpose applications. Low bias current (±4pA) allows use with high impedance sources. Gain can be set from 1V to 10,000V/V with a single external resistor. Internal input prot.
