Operating on a very low 5.1mA supply current, the OPA691 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 OPA691 can deliver a 1V to 4V output swing with over 150mA drive current and 190MHz bandwidth. This combination of features makes the OPA691 an ideal RGB line driver or single-supply Analog-to-Digital Converter (ADC) input driver. The OPA691’s low 5.1mA supply current is precisely trimmed at 25°C. This trim, along with low drift over-temperature, ensures lower maxim...
