A new internal architecture provides slew rate and full-power bandwidth previously found only in wideband current feedback op amps. A new output stage architecture delivers high currents with a minimal headroom requirement. These combine to give exceptional single-supply operation. Using a single +5V supply, the OPA690 can deliver a 1V to 4V output swing with over 150mA drive current and 150MHz bandwidth. This combination of features makes the OPA690 an ideal RGB line driver or single-supply Analog-to-Digital Converter (ADC) input driver. +5V R1 R1 2.5V 0.1µF C1 VI R2 3 2 8 OPA690 4 R5 20Ω C4 10µF C2 R4 20Ω The OPA690’s low 5.5mA supply current is precisely trimmed at 25°C.
