INA128 Low Power Instrumentation Amplifier IC – DIP-8 Package
The INA128 and INA129 are low-power, general-purpose instrumentation amplifiers offering excellent accuracy. The versatile 3-op amp design and small size make these amplifiers 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 INA128 provides an industry-standard gain equation; the INA129 gain equation is compatible with the AD620. The INA12x is available in 8-pin plastic DIP and SO-8 surface-mount packages, specified for the –40°C to +85°C temperature range. The INA128 is also available in a dual configuration, the INA2128. This product is known as INA128P, INA128PG4, INA128UA, INA128UA/2K5, INA128U, INA128U/2K5, INA128PA, INA128UAE4, INA128UAG4.
