500MHz Rail-to-Rail Amplifier

The EL8302 represents a triple rail-to-rail amplifier with a 3dB bandwidth of 500MHz and slew rate of 600V/µs. Running off a very low supply current of 5.6mA per channel, the EL8302 also features inputs that go to 0.15V below the V

- rail.

S

The EL8302 includes a fast-acting disable/power-down circuit. With a 25ns disable and a 200ns enable, the EL8302 is ideal for multiplexing applications.

The EL8302 is designed for a number of general purpose video, communication, instrumentation, and industrial applications. The EL8302 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.
