Description

The OPA3691 sets a new level of performance for broadband, triple current-feedback op amps. Operating on a very low 5.1mA/ch supply current, the OPA3691 offers a slew rate and output power normally associated with a much higher supply current. A new output stage architecture delivers a high output current with minimal voltage headroom and crossover distortion. This gives exceptional single-supply operation. Using a single +5V supply, the OPA3691 can deliver a 1V to 4V output swing with over 120mA drive current and 150MHz bandwidth. This combination of features makes the OPA3691 an ideal RGB line driver or single-supply Analog-to-Digital Converter (ADC) input driver.

The OPA3691‘s low 5.
