The ADA4077-2ARMZ-RL is a low-supply-current, low-noise, bi-polar, JFET-input operational amplifier with a rail-to-rail output and input range. It is suited for a wide range of instrumental and measurement applications, such as audio amplifiers, RF amplifiers, active filters, and instrumentation amplifiers. This device is designed with a low quiescent operating current, making it suitable for battery-operated applications that require extremely low power consumption.

At its core, the ADA4077-2ARMZ-RL is a differential voltage amplifier and is composed of an input stage, a first differential amplifier stage, an output stage, and a slew rate control circuit. The input stage creates a differential voltage from the input source. This voltage is input to the first differential amplifier stage, comprised of a pair of identical transistors in a differential amplifier configuration. This stage amplifies the differential voltage and is the main amplification circuit. The output of this stage drives the output stage, which is a single-ended, class-AB amplifier.

The ADA4077-2ARMZ-RL is also equipped with a slew rate control circuit. This circuit determines the maximum speed of the amplifier. Its purpose is to ensure that the amplifier’s output does not overshoot or undershoot its control signal. This helps to ensure linear operation over the operating range of the amplifier.

The ADA4077-2ARMZ-RL is suitable for a wide range of instrumentation, operational amplifier, buffer amplifier, and audio applications. Its low noise and low power consumption make it an attractive choice for battery-powered applications, and its small size enables easy integration into almost any design.
