Rail-to-Rail Amplifier

® EL8300 Data Sheet May 20, 2005 FN7347.2 200MHz Rail-to-Rail Amplifier The EL8300 represents a triple rail-to-rail amplifier with a 3dB bandwidth of 200MHz and slew rate of 200V/µs. Running off a very low supply current of 2mA per channel, the EL8300 also features inputs that go to 0.15V below the VS- rail. The EL8300 includes a fast-acting disable/power-down circuit. With a 25ns disable and a 200ns enable, the EL8300 is ideal for multiplexing applications. The EL8300 is designed for a number of general purpose video, communication, instrumentation, and industrial applications. The EL8300 is available in an 16-pin SO and 16-pin QSOP packages and is specified for operation over the -40°C to +85°C temperature range.
