Description

The OPA777UA is a CMOS operational amplifier that operates on a 2.1V (Min.) single supply. It has a rail-to-rail output that can drive a 100kΩ load, ensuring an output voltage accuracy of ±3mV. The OPA777UA has a low quiescent current of 20μA per amplifier, a low offset voltage of up to 125μV, a low input bias current of 1pA, and a high open-loop gain of 115dB. It features completely independent circuitry for lowest crosstalk and freedom from interaction. The OPA777UA is designed for battery-powered applications and has a common-mode range extending to the negative supply, making it ideal for single-supply applications. It is also suitable for portable devices, high-impedance applications, photodiode, pre-amps, precision integrators, medical instruments, and test equipment.
