125MHz Single Supply, Clamping Op Amp

Features

The EL2257 is a single supply op amp.

Prior single supply op amps have

generally been limited to bandwidths

• Specified for +3V, +5V, or ± 5V applications

• Power-down to 0µA

• Output voltage clamp

and slew rates one-fourth of that of the EL2257. 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 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 EL2257 will output ±100mA and will

operate with single supply voltages as low as 2.7V, making

them ideal for portable, low power applications.

• Large input common-mode range 0V < V

< V - 1.2V

• Output swings to ground without saturating

• -3dB bandwidth = 125MHz

• ±0.1dB bandwidth = 30MHz

• Low supply current = 5mA

• Slew rate = 275V/µs

• Low offset voltage = 4mV max

• Output current = ±100mA

• High open loop gain = 80dB

• Differential gain = 0.05%

The EL2257 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.

• Differential phase = 0.05°

Applications

• Video amplifiers

The EL2257 also has an output voltage clamp feature. This

clamp is a fast recovery (< 7ns) 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.

• PCMCIA applications

• A/D drivers

• Line drivers

• Portable computers

• High speed communications

• RGB printer, fax, scanner applications

• Broadcast equipment

• Active filtering

The EL2257 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 EL2150 and EL2157. For space-saving, industry-

standard pinout dual and quad applications, see the EL2250

and EL2450.
