OPA2251UA

The OPA241, OPA2241, OPA4241 (OPAx241),
and OPA251, OPA2251, OPA4251 (OPAx251)
devices are specifically designed for battery-powered,
portable applications. In addition to very low power
consumption (25μA), these amplifiers feature low
offset voltage, rail-to-rail output swing, high commonmode rejection, and high open-loop gain.
The OPAx241 series is optimized for operation at
low power supply voltage while the OPAx251 series
is optimized for high-power supplies. Both series
can operate from either single (2.7V to 36V) or
dual supplies (±1.35V to ±18V). The input commonmode voltage range extends 200mV less than the
negative supply—an excellent choice for single-supply
applications.
The OPAx241 and OPAx251 are unity-gain stable
and can drive large capacitive loads. Special design
considerations makes sure that these products are
easy to use. High performance is maintained as the
amplifiers swing to the specified limits. Because the
initial offset voltage (±250μV max) is so low, user
adjustment is usually not required. However, external
trim pins are provided for special applications (single
versions only).
The OPAx241 and OPAx251 are fully specified from
−40°C to +85°C and operate from −55°C to +125°C.
