DESCRIPTION

The OPA241 series and OPA251 series are specifically

designed for battery powered, portable applications. In addition to very low power consumption (25μA), these amplifi-

ers feature low offset voltage, rail-to-rail output swing, high common-mode rejection, and high open-loop gain.

The OPA241 series is optimized for operation at low power supply voltage while the OPA251 series is optimized for

high power supplies. Both 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.

They are unity-gain stable and can drive large capacitive loads. Special design considerations assure that these products are easy to use. High performance is maintained as the

amplifiers swing to their 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 OPA241 and OPA251 (single versions) are available in standard 8-pin DIP and SO-8 surface-mount packages. The OPA2241 and OPA2251 (dual versions) come in 8-pin DIP and SO-8 surface-mount packages. The OPA4241 and OPA4251 (quad versions) are available in 14-pin DIP and

SO-14 surface-mount packages. All are fully specified from –40°C to +85°C and operate from –55°C to +125°C.
