EL8202, EL8203, EL8403
500MHz Rail-to-Rail Amplifiers
The EL8202, EL8203, and EL8403
represent rail-to-rail amplifiers with a
-3dB bandwidth of 500MHz and slew
rate of 600V/s. Running off a very low supply current of
5.6mA per channel, the EL8202, EL8203, and EL8403 also
feature inputs that go to 0.15V below the V
S
- rail. The
EL8202 and EL8203 are dual channel amplifiers. The
EL8403 is a quad channel amplifier.
The EL8202 includes a fast-acting disable/power-down
circuit. With a 25ns disable and a 200ns enable, the EL8202
is ideal for multiplexing applications.
The EL8202, EL8203, and EL8403 are designed for a
number of general purpose video, communication,
instrumentation, and industrial applications. The EL8202 is
available in a 10-pin MSOP package, the EL8203 in an 8-pin
SO package, and the EL8403 in 14-pin SO and 16-pin
QSOP packages. All are specified for operation over the
-40C to +85C temperature range.
