Overview
The ADA4853-3YCPZ-R7 is a low-power, rail-to-rail output, video operational amplifier produced by Analog Devices Inc. This device is part of the ADA4853 series, which includes the ADA4853-1, ADA4853-2, and ADA4853-3 models. The ADA4853-3YCPZ-R7 is designed for high-speed applications, particularly in video and consumer electronics, offering excellent performance and versatility despite its low power consumption.
It operates at supply voltages ranging from 2.65 V to 5 V, using only 1.4 mA of supply current per amplifier. The amplifier also features a power-down mode that reduces the supply current to less than 1.5 μA, making it ideal for battery-powered devices.
