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 SOT23-6 package and is specified over the
extended –40°C to 125°C range.
