Overview
The OPA355NA/3K is a high-speed voltage-feedback CMOS Operational Amplifier produced by Texas Instruments. It features a digital shutdown (enable) function, which provides power savings during idle periods and places the output in a high-impedance state to support output multiplexing. This amplifier is unity-gain stable and capable of driving large output currents. The OPA355NA/3K is designed for applications requiring wide bandwidth, such as video processing, ultrasound, and optical networking.
