The OPA251UA is a single MicroPower Operational Amplifier specifically designed for battery-powered applications. In addition to very low power consumption (25μA), this amplifier features low offset voltage, rail-to-rail output swing, high common-mode rejection and high open-loop gain. The OPA251 series is optimized for operation at high power supply voltage. The input common-mode voltage range extends 200mV below the negative supply-ideal for single-supply applications. It is unity-gain stable and can drive large capacitive loads. Special design considerations assure that this product is easy to use. High performance is maintained as the amplifier swing to their specified limits. Because the initial offset voltage (±250μV maximum) is so low, user adjustment is usually not required. However, external trim pins are provided for special applications.
