Automotive 2.5V, 200MHz GBW, CMOS Single Op Amp With Shutdown



The OPA355-Q1 device is a high-speed, voltage-feedback CMOS operational amplifier designed for applications requiring wide bandwidth. The OPA355-Q1 device is unity-gain stable and can 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 a high-impedance state to support output multiplexing. The differential gain is 0.02% and the differential 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 low as 2.5 V (±1.25 V) and up to 5.5 V (±2.75 V). The common-mode input range for the OPA355-Q1 device extends 100 mV below ground and up to 1.5 V from V+. The output swing is within 100 mV of the rails, supporting wide dynamic range.

The OPA355-Q1 device is available in a single SOT-23-6 package and is specified over the extended –40°C to +125°C temperature range.
