GENERAL DESCRIPTION

The AD8005 is an ultralow power, high speed amplifier with a wide signal bandwidth of 170 MHz 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.
