General Description
The EL2150C EL2157C are the electronics industry’s fastest
single supply op amps available Prior single supply op amps
have generally been limited to bandwidths and slew rates
that of the EL2150C EL2157C The 125 MHz bandwidth
275 V
ms
slew rate and 0 05% 0 05 differential gain differen-
tial phase makes this part ideal for single or dual supply video
speed applications With its voltage feedback architecture this
amplifier can accept reactive feedback networks allowing them
to be used in analog filtering applications The inputs can sense
signals below the bottom supply rail and as high as 1 2V below
the top rail Connecting the load resistor to ground and operat-
ing from a single supply the outputs swing completely to
ground without saturating The outputs can also drive to within
1 2V of the top rail The EL2150C EL2157C will output
g
100
mA and will operate with single supply voltages as low as 2 7V
making it ideal for portable low power applications
The EL2157C has a high speed disable feature Applying a low
logic level to this pin reduces the supply current to 0
mA
within
50 ns This is useful for both multiplexing and reducing power
consumption
The EL2157C also has an output voltage clamp feature This
clamp is a fast recovery (
k
7 ns) output clamp that prevents the
output voltage from going above the preset clamp voltage This
feature is desirable for A D applications as A D converters can
require long times to recover if overdriven
For applications where board space is critical the EL2150C is
available in the tiny 5 lead SOT23 package which has a foot-
print 28% the size of an 8 lead SOIC The EL2150C EL2157C
are also both available in 8 pin plastic DIP and SOIC packages
All parts operate over the industrial temperature range of
