3 Description

The OPA357 series of high-speed, voltage-feedback

CMOS operational amplifiers is designed for video

and other applications requiring wide bandwidth.

These devices are unity-gain stable and can drive

large output currents. Differential gain is 0.02% and

differential phase is 0.09°. Quiescent current is only

4.9 mA per channel.

The OPA357 series of op amps is optimized for

operation on single or dual supplies as low as 2.5 V

(±1.25 V) and up to 5.5 V (±2.75 V). Common-mode

input range extends beyond the supplies. The output

swing is within 100 mV of the rails, supporting wide

dynamic range.

The single version (OPA357) comes in the miniature

SOT23-6 package. The dual version (OPA2357) is

offered in the VSSOP-10 package.

The dual version features completely independent

circuitry for lowest crosstalk and freedom from

interaction. Both versions are specified over the

extended –40°C to +125°C temperature range.
