Overview
The AD8057AR from Analog Devices Inc. is a high-performance, single-channel voltage feedback operational amplifier. It is known for its excellent balance between cost and performance, making it ideal for a wide range of applications. The AD8057AR features a bandwidth and slew rate typically found in current feedback amplifiers but with the advantages of voltage feedback architecture. This amplifier is designed for low power consumption, with a quiescent current of 5.4 mA to 7.0 mA, and operates over a wide supply voltage range from 3 V to 12 V. It is available in both 8-lead SOIC and 5-lead SOT-23 packages, and is rated for an industrial temperature range of -40°C to +85°C.
