Description

The AD8005 is an ultralow power, high-speed amplifier with a wide signal bandwidth of 170MHz and slew rate of 280 V/µs. This performance is achieved while consuming only 400 µA of quiescent supply current. These features increase the operating time of high-speed battery-powered systems without reducing dynamic performance.

The current feedback design results in gain flatness of 0.1 dB to 30MHz while offering differential gain and phase errors of 0.11% and 0.4°. Harmonic distortion is low over a wide bandwidth with THDs of 63 dBc at 1MHz and 50 dBc at 10MHz. Ideal features for a signal conditioning amplifier or buffer to a high-speed A-to-D converter in portable video,medical or communication systems. The AD8005 is characterized for +5 V and ±5 V supplies and will operate over the industrial temperature range of 40°C to +85°C. The amplifier is supplied in 8-lead plastic DIP, 8-lead SOIC and 5-lead SOT-23 packages.
