Description

General part information

INA128 Series

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. 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 with a 50-kΩ resistor. The INA129 gain equation uses a 49.4-kΩ resistor to allow for drop-in replacements of comparable devices.

The INA12x are available in plastic DIP and surface-mount packages, specified for the –40°C to +85°C temperature range. The INA128 is also available in a dual configuration, theINA2128.
