INA592IDRCR

The INA592 device is a low-power, wide-bandwidth differential amplifier composed of a precision operational amplifier (op amp) and a precision resistor network. The excellent tracking performance (TCR) of the resistors maintains gain accuracy and common-mode rejection over the full temperature range. Unique characteristics such as low offset voltage of 40 μV (maximum), low temperature drift (2 μV/°C maximum), high slew rate (18V/μs), and high capacitive load drive up to 500pF make the INA592 a robust, high-performance differential amplifier suitable for various high-voltage industrial applications. The common-mode range of the internal operational amplifier extends to the negative supply, enabling the device to operate in single-supply applications. The device operates from a single supply (4.5V to 36V) or dual supplies (±2.25V to ±18V). Differential amplifiers form the cornerstone of many commonly used circuits. The INA592 provides this circuit functionality without the need for expensive precision resistor networks.
