The OPA4336EA/250G4 is a quad MicroPower CMOS Operational Amplifier designed for battery-powered applications. It operate on a single supply with operation as low as 2.1V. The output is rail-to-rail and swings to within 3mV of the supplies with a 100k load. The common-mode range extends to the negative supply-ideal for single-supply applications. Quad version has identical specifications for maximum design flexibility. In addition to small size and low quiescent current (20μA/amplifier), it feature high open-loop gain (115dB). Quad design feature completely independent circuitry for lowest crosstalk and freedom from interaction.
