The INA597 is a low-power, wide-bandwidth, difference amplifier for cost-sensitive applications. The INA597 consists of a precision operational amplifier (op amp) and a precision resistor network. Excellent tracking of resistors maintains gain accuracy and common-mode rejection over temperature. Unique features such as low offset (200 µV, maximum), low offset drift (5 µV/°C maximum) high slew rate (18 V/µs), and high capacitive load drive of up to 500 pF make the INA597 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, and enables 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 INA597 provides this circuit function without using an expensive precision resistor network.
The INA597 is available in 8-pin VSSOP surface-mount package, and is specified for operation over the industrial temperature range of –40°C to +125°C.
