High-precision (40-µV offset), 2-MHz, 88-dB CMRR, low-power, e-trim™ difference amplifier

The INA592 device is a low-power, wide

bandwidth difference amplifier consisting of a precision operational amplifier (op

amp) and a precision resistor network. Excellent tracking of resistors (TCR)

maintains gain accuracy and common-mode rejection over temperature. Unique features

such as low offset 40 µV (maximum), low offset drift (2 µV/°C maximum) high slew

rate (18 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-mode range of the internal op amp extends to the negative

supply, enabling the device to operate in single-supply applications. The device

operates on single (4.5 V to 36 V) or dual supplies (±2.25 V to ±18 V).

The difference amplifier is the

foundation of many commonly used circuits. The INA592 provides this circuit function

without using an expensive precision resistor network.
