Product Summary
The OPA251UA/2K5 is a single-supply, micropower operational amplifier specifically designed for battery powered, portable applications. In addition to very low power consumption (25mA), the amplifier OPA251UA/2K5 features low offset voltage, rail-to-rail output swing, high common-mode rejection, and high open-loop gain. The OPA241UA is optimized for operation at low power supply voltage while the OPA251UA/2K5 is optimized for high power supplies. The device can operate from either single (+2.7V to +36V) or dual supplies (±1.35V to ±18V). The input common-mode voltage range extends 200mV below the negative supply-ideal for single-supply applications. The OPA251UA/2K5 is unity-gain stable and can drive large capacitive loads. Special design considerations assure that the product is easy to use. High performance is maintained as the amplifiers swing to their specified limits.
