The OPA336UA is a single 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 100kR load. The common-mode range extends to the negative supply-ideal for single-supply applications. Single version has identical specifications for maximum design flexibility. In addition to small size and low quiescent current (20µA/amplifier), it features low offset voltage (125µV maximum), low input bias current (1pA) and high open-loop gain (115dB).
