DESCRIPTION
The OPA357 series of high-speed, voltage-feedback
CMOS operational amplifiers are designed for video and
other applications requiring wide bandwidth. They 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 4.9mA per channel.
The OPA357 series op amps are optimized for operation
on single or dual supplies as low as 2.5V (±1.25V) and up
to 5.5V (±2.75V). Common-mode input range extends
beyond the supplies. The output swing is within 100mV of
the rails, supporting wide dynamic range.
For applications requiring the full 100mA continuous
output current, the single SO-8 PowerPAD version is
available.
The single version (OPA357), comes in the miniature
SOT23-6 and SO-8 PowerPAD packages. The dual
version (OPA2357) is offered in the MSOP-10 package.
The dual version features completely independent
circuitry for lowest crosstalk and freedom from interaction.
All are specified over the extended −40°C to +125°C
temperature range.
