The INA129 is a low power, general purpose instrumentation amplifier offering excellent accuracy. The versatile 3-op amp design and small size make it ideal for a wide range of applications. Current-feedback input circuitry provides wide bandwidth even at high gain (200 kHz at G = 100).
A single external resistor sets any gain from 1 to 10,000. The INA129 provides an industry-standard gain equation; the INA129 gain equation is compatible with the AD620.
The INA129 is laser trimmed for very low offset voltage, drift and high common-mode rejection (113 dB at G ≥ 100). It operates with power supplies as low as ±2.25 V, and quiescent current is only 750 µA - ideal for battery operated systems.
