А instrumentation amplifier is designed for precision voltage amplification with high signal transmission accuracy. Due to the high input impedance, low offset voltage, signal transmission accuracy and high degree of common-mode rejection, the chip is ideal for various sensors and converters of physical quantities to voltage. Low current consumption and a wide range of supply voltages allow the chip to be used in battery-powered devices.
