The INA121P 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 10000V/V with a single external resistor. Internal input protection can withstand up to ±40V without damage. The INA121 is laser-trimmed for very low offset voltage (±200mV) and high common-mode rejection (106dB at G=100). It operates on power supplies as low as ±2.25V (+4.5V), allowing use in battery operated and single 5V systems. Quiescent current is only 450mA.
