APPLICATIONS

Power-Sensitive, High-Speed Systems Battery Powered Equipment Loop/Remote Power Systems Communication or Video Test Systems Portable Medical Instruments FUNCTIONAL BLOCK DIAGRAM 8-Lead Plastic DIP and SOIC AD8005NC –IN +IN –VS NC +VS OUT NC NC = NO CONNECT 5-Lead SOT-23 AD8005 –VS +VS –IN OUT +IN PRODUCT DESCRIPTION The AD8005 is an ultralow power, high-speed amplifier with a wide signal bandwidth of 170 MHz and slew rate of 280 V/ ms. This performance is achieved while consuming only 400 mA of quiescent supply current. These features increase the operating time of high-speed battery-powered systems without reducing dynamic performance.
