EL8302
FN7348.2
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
VS- rail.
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.

NOTE: Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with
both SnPb and Pb-free soldering operations. Intersil Pb-free products
are MSL classified at Pb-free peak reflow temperatures that meet or
exceed the Pb-free requirements of IPC/JEDEC J STD-020.
