General Description
The EL2250C/EL2450C are part of a family of the electronics indus-
tries fastest single supply op amps available. Prior single supply op
amps have generally been limited to bandwidths and slew rates to that
of the EL2250C/EL2450C. The 125MHz bandwidth, 275V/µs 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 feed-
back 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 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 EL2250C/EL2450C will output
±100mA and will operate with single supply voltages as low as 2.7V,
making them ideal for portable, low power applications.
The EL2250C/EL2450C are available in PDIP and SO packages in
industry standard pin outs. Both parts operate over the industrial tem-
perature range of -40°C to +85°C, and are part of a family of single
supply op amps. For single amplifier applications, see the
EL2150C/EL2157C. For dual and triple amplifiers with power down
and output voltage clamps, see the EL2257C/EL2357C.
