200MHz Rail-to-Rail Amplifiers
The EL8100 and EL8101 represent
single rail-to-rail amplifiers with a
-3dB bandwidth of 200MHz and slew
rate of 200V/µs. Running off a very low 2mA supply current,
the EL8100 and EL8101 also feature inputs that go to 0.15V
below the V
S
- rail.
The EL8100 includes a fast-acting disable/power-down
circuit. With a 25ns disable and a 200ns enable, the EL8100
is ideal for multiplexing applications.
The EL8100 and EL8101 are designed for a number of
general purpose video, communication, instrumentation, and
industrial applications. The EL8100 is available in 8-pin SO
and 6-pin SOT-23 packages and the EL8101 is available in a
5-pin SOT-23 package. All are specified for operation over
the -40°C to +85°C temperature range.
Features
• 200MHz -3dB bandwidth
• 200V/µs slew rate
• Low supply current = 2mA
• Supplies from 3V to 5.5V
• Rail-to-rail output
• Input to 0.15V below V
S
-
• Fast 25ns disable (EL8100 only)
• Low cost
Applications
• Video amplifiers
• Portable/hand-held products
• Communications devices
