EL2257C

125MHz Single Supply, Clamping Op Amp

General Description

The EL2257C is a single supply op amp. Prior single supply op amps

have generally been limited to bandwidths and slew rates one-fourth

of that of the EL2257C. 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 volt-

age 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

operating 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 EL2257C will output ±100mA and will operate

with single supply voltages as low as 2.7V, making them ideal for por-

table, low power applications.

The EL2257C has a high speed disable feature. Applying a low logic

level to all ENABLE pins reduces the supply current to 0µA within

50ns. Each amplifier has its own ENABLE pin. This is useful for both

multiplexing and reducing power consumption.

The EL2257C also has 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 is available in 14-pin SO (0.150") and 14-pin PDIP

packages and operates over the industrial temperature range of -40°C

to +85°C. For single amplifier applications, see the EL2150C and

EL2157C. For space-saving, industry-standard pinout dual and quad

applications, see the EL2250C and EL2450C.
