Overview
The AD8012ARMZ-REEL, produced by Analog Devices Inc., is a dual, low power, current feedback amplifier. It is designed to provide high performance with minimal power consumption, making it ideal for high frequency, wide dynamic range systems. Each amplifier in the AD8012 consumes only 1.7 mA of supply current, yet offers exceptional AC specifications such as a 20 ns settling time and a 2,250 V/µs slew rate. The device is available in standard 8-lead SOIC or MSOP packages and operates over the industrial temperature range of –40°C to +85°C.
