The OPA355-Q1 device is a high-speed, voltage-feedback CMOS operational amplifierdesigned for applications requiring wide bandwidth. The OPA355-Q1 device is unity-gain stable andcan drive large output currents. In addition, the OPA355-Q1 device has a digital shutdown (enable)function. This feature provides power saving during idle periods and places the output in ahigh-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 OPA355-Q1 device is optimized for operation on single supply or dual supplies as lowas 2.5 V (±1.25 V) and up to 5.5 V (±2.75 V). The common-mode input range for the OPA355-Q1 deviceextends 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 OPA355-Q1 device is available in a single SOT-23-6 package and is specified over theextended –40°C to +125°C temperature range.
