INA129U - Texas Instruments

INA129U Low-Power Instrumentation Amplifiers

The INA128 and INA129 (INA12x) are low-power, general-purpose instrumentation amplifiers that offer excellent accuracy. The versatile three op amp design and small size make these amplifiers an excellent choice for a wide range of applications. Currentfeedback input circuitry provides wide bandwidth even at high gain (200 kHz at G = 100). A single external.
