Description for the INA2128
The INA2128 is a dual, low-power, general-purpose instrumentation amplifier (IA) offering excellent accuracy. The versatile three-op-amp design and small size make this device an excellent choice 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). The device operates with power supplies as low as ±2.25V, and quiescent current is only 700µA per IA—a great choice for battery-operated and multiple-channel systems.
The INA2128 is available in an SOIC-16 package, and is specified from –40°C to +85°C.
