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.
