General Description
The EL2257C/EL2357C are supply op amps. Prior single supply op
amps have generally been limited to bandwidths and slew rates 1/4
that of the EL2257C/EL2357C. The 125 MHz bandwidth, 275 V/s
slew rate, and 0.05%/0.05° differential gain/differential 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 appli-
cations. 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 operating from a single supply, the outputs swing com-
pletely to ground without saturating. The outputs can also drive to
within 1.2V of the top rail. The EL2257C/EL2357C will output
±100 mA and will operate with single supply voltages as low as 2.7V,
making them ideal for portable, low power applications.
The EL2257C/EL2357C have a high speed disable feature. Applying a
low logic level to all ENABLE pins reduces the supply current to 0 A
within 50 ns. Each amplifier has its own ENABLE pin. This is useful
for both multiplexing and reducing power consumption.
The EL2257C/EL2357C also have an output voltage clamp feature.
This clamp is a fast recovery (<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.
The EL2257C/EL2357C are available in plastic DIP and SOIC pack-
ages. Both parts operate over the industrial temperature range of -40°C
to +8 5° C . For s i ngle a m plif ie r ap pli c ations , s e e the
EL2150C/EL2157C. For space saving, industry standard pin out dual
and quad applications, see the EL2250C/EL2450C.
