Introduction

AI Translation

The INA128 and INA129 are low power, general purpose instrumentation amplifiers 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 INA129 gain equation is compatible with the AD620. The INA128/INA129 is laser trimmed for very low offset voltage (50μV), drift (0.5μV/°C) and high common-mode rejection (120dB at a ≥ 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/INA129 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.
