INA129-EP Low-Power Instrumentation Amplifiers

The INA129-EP device is a low power, generalpurpose instrumentation amplifier offering excellent accuracy. The versatile 3-op amp design and small size make the device 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 10,0.
