3D Model

The INA128 is low power, general purpose instrumentation amplifier 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 INA128 is laser trimmed for very low offset voltage (50µV), drift (0.5µV/°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 700µA—ideal for battery-operated systems. Internal input protection can withstand up to ±40V without damage. The INA128 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 article provides you with a basic overview of the INA128, including its pin descriptions, features and specifications, etc., to help you quickly understand what INA128 is.
