250MHz, Rail-to-Rail I/O, CMOS
Operational Amplifier with Shutdown
FD EATURES
DESCRIPTION
UNITY-GAIN BANDWIDTH: 250MHz
WIDE BANDWIDTH: 100MHz GBW
HIGH SLEW RATE: 150V/ms
LOW NOISE: 6.5nV/√Hz
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.

RAIL-TO-RAIL I/O
HIGH OUTPUT CURRENT: > 100mA
EXCELLENT VIDEO PERFORMANCE:
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.
Diff Gain: 0.02%, Diff Phase: 0.095
0.1dB Gain Flatness: 40MHz

LOW INPUT BIAS CURRENT: 3pA
QUIESCENT CURRENT: 4.9mA
THERMAL SHUTDOWN
For applications requiring the full 100mA continuous
output current, the single SO-8 PowerPAD version is
available.
SUPPLY RANGE: 2.5V to 5.5V
SHUTDOWN I < 6mA
Q
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.
MicroSIZE AND PowerPAD PACKAGES
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.
