The INA2128 is a dual, low power, general purpose instrumentation amplifier offering excellent accuracy. Its versatile 3-op amp design and small size make it 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. Internal input protection can withstand up to ±40V without damage.
●The INA2128 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 per IAideal for battery operated and multiple-channel systems.
●The INA2128 is available in 16-pin plastic DIP, and SOL-16 surface-mount packages, specified for the -40°C to +85°C temperature range.
