The Texas Instruments OPA241 series and OPA251 series 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 OPA241 and OPA251 (single versions) are available in standard 8-pin DIP and SO-8 surface-mount packages.
