200MHz Rail-to-Rail Amplifiers
The EL8200, EL8201, and EL8401 represent rail-to-rail
amplifiers with a -3dB bandwidth of 200MHz and slew rate of
200V/µs. Running off a very low supply current of 2mA per
channel, the EL8200, EL8201, and EL8401 also feature
inputs that go to 0.15V below the VS- rail. The EL8200 and
EL8201 are dual channel amplifiers. The EL8401 is a quad
channel amplifier.
The EL8200 includes a fast-acting disable/power-down
circuit. With a 25ns disable and a 200ns enable, the EL8200
is ideal for multiplexing applications.
The EL8200, EL8201, and EL8401 are designed for a
number of general purpose video, communication,
instrumentation, and industrial applications. The EL8200 is
available in a 10-pin MSOP package, the EL8201 in an 8-pin
SO package, and the EL8401 in a 14-pin SO and 16-pin
QSOP packages. All are specified for operation over the
-40°C to +85°C temperature range.
