Overview
The AD8054AR, produced by Analog Devices Inc., is a quad high-speed, rail-to-rail operational amplifier. It is part of the AD8051/AD8052/AD8054 family, which includes single, dual, and quad configurations. These amplifiers are fabricated using Analog Devices' proprietary eXtra-Fast Complementary Bipolar (XFCB) process, enabling high-speed performance and low power consumption.
The AD8054AR operates on +3 V, +5 V, or ±5 V supplies, offering true single-supply capability with an input voltage range extending 200 mV below the negative rail and within 1 V of the positive rail. This makes it versatile for various high-speed applications, including video electronics, cameras, and active filters.
