INA592 - High-Precision, Wide-Bandwidth e-trim Difference Amplifier

Updated : 2020-01-09 14:22:37
Description

The INA592 device is a low-power, wide bandwidth-difference amplifier consisting of aprecision operational amplifier (op amp) and a precision resistor network. Excellent TCR trackingof the resistors maintains gain accuracy and common-mode rejection over temperature. Uniquefeatures such as low offset 40 µV (maximum), low offset drift (1.5 µV/°C maximum) high slew rate(20 V/µs), and high capacitive load drive of up to 500 pF make the INA592 a robust,high-performance difference amplifier for high-voltage industrial applications. The common-moderange of the internal op amp extends to the negative supply, enabling the device to operate insingle-supply applications. The device operates on single (2.7 V to 36 V) or dual supplies (±1.35 Vto ±18 V).

The differential amplifier is the foundation of many commonly used circuits. The INA592provides this circuit function without using an expensive precision resistor network. The INA592 isavailable in 8-pin VSSOP surface-mount package and is specified for operation over the extendedindustrial temperature range, –40°C to +125°C.
