Overview
The AD8012AR-REEL7, produced by Analog Devices Inc., is a dual, low power, current feedback amplifier. It is designed to provide a high bandwidth of 350 MHz while consuming only 1.7 mA per amplifier. This amplifier is ideal for high-frequency, wide dynamic range systems where low distortion and high speed are essential, and low power consumption is critical. The AD8012AR-REEL7 is available in standard 8-lead SOIC and MSOP packages and operates over the industrial temperature range of –40°C to +85°C.
