Texas Instruments INA128

the ina128 and ina129 are low power general purpose instrumentation amplifiers offering excellent accuracy. the versatile 3-op amp design and small size make them ideal for a wide range of applications. current-feedback input circuitry provides wide bandwidth even at high gain (200khz at g = 100). a single external resistor sets any gain from 1 to 10 000. the ina128 provides an industry-standard gain equation; the ina129 gain equation is compatible with the ad620. the ina128/ina129 is laser trimmed for very low offset voltage (50v) drift (0.5v/c) and high common-mode rejection (120db at g = 100). it operates with power supplies as low as 2.25v and quiescent current is only 700aideal for battery-operated systems. view all in datasheet
