500MHz Rail-to-Rail Amplifiers
The EL8102 and EL8103 represent single rail-to-rail amplifiers with a -3dB bandwidth of 500MHz and slew rate of 600V/s. Running off a very low 5.6mA supply current, the EL8102 and EL8103 also feature inputs that go to 0.15V below the VS- rail. The EL8102 includes a fast-acting disable/power-down circuit. With a 25ns disable and a 200ns enable, the EL8102 is ideal for multiplexing applications. The EL8102 and EL8103 are designed for a number of general purpose video, communication, instrumentation, and industrial applications. The EL8102 is available in 8-pin SO and 6-pin SOT-23 packages and the EL8103 is available in a 5-pin SOT-23 package. All are specified for operation over the -40C to +85C temperature range.
Features
* 500MHz -3dB bandwidth * 600V/s slew rate * Low supply current = 5.6mA * Supplies from 3V to 5.5V * Rail-to-rail output * Input to 0.15V below VS* Fast 25ns disable (EL8102 only) * Low cost
Applications
* Video amplifiers * Portable/hand-held products * Communications devices
