Overview
The AD8012ARZ-REEL7 is a dual, low power, current feedback amplifier produced by Analog Devices Inc. This amplifier is designed to provide a high bandwidth of 350 MHz while consuming only 1.7 mA of supply current per amplifier. It is ideal for high frequency, wide dynamic range systems where low distortion and high speed are crucial, and low power consumption is essential. The AD8012 is available in 8-lead SOIC-N and MSOP packages and operates over an industrial temperature range of -40°C to +85°C.
