OPA2355 - 2.5V, 200MHz GBW, CMOS Dual Op Amp With Shutdown

The OPA355 series of high-speed, voltage-feedback CMOS operational amplifiers aredesigned for video and other applications requiring wide bandwidth. The OPA355 series is unity-gainstable and can drive large output currents. In addition, the OPAx355 series has a digital shutdown(enable) function. This feature provides power saving during idle periods and places the output ina high-impedance state to support output multiplexing. The differential gain is 0.02% and thedifferential phase is 0.05°. The quiescent current is 8.3 mA per channel.

The OPAx355 series is optimized for operation on single supply or dual supplies as low as2.5 V (±1.25 V) and up to 5.5 V (±2.75 V). The common-mode input range for the OPAx355 seriesextends 100 mV below ground and up to 1.5 V from V+. The output swing is within 100 mV of therails, supporting wide dynamic range.

The OPAx355 series is available in single (SOT-23-6 and SO-8), dual(VSSOP-10), and triple (TSSOP-14 and SO-14) versions. Multichannel versions feature completelyindependent circuitry for lowest crosstalk and freedom from interaction. All packages are specifiedfrom –40°C to +125°C.
