DESCRIPTION

The OPA355 series high-speed, voltage-feedback CMOS

operational amplifiers are designed for video and other

applications requiring wide bandwidth. The OPA355 is unity-

gain stable and can drive large output currents. In addition,

the OPA355 has a digital shutdown (Enable) function. This

feature provides power savings during idle periods and

places the output in a high-impedance state to support output

multiplexing. Differential gain is 0.02% and differential phase

is 0.05

°. Quiescent current is only 8.3mA per channel.

The OPA355 is 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 for the OPA355 extends 100mV

below ground and up to 1.5V from V+. The output swing is

within 100mV of the rails, supporting wide dynamic range.

The OPA355 series is available in single (SOT23-6 and

SO-8), dual (MSOP-10), and triple (TSSOP-14 and SO-14)

versions. Multichannel versions feature completely indepen-

dent circuitry for lowest crosstalk and freedom from interac-

tion. All are specified over the extended –40

°C to +125°C

range.
