Description

General part information

OPA4241 Series

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 common-mode 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 common-mode 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).
