Operating on a very low 5.1mA/ch supply current, the OPA2691 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 OPA2691 can deliver a 1V to 4V output swing with over 150mA drive current and 190MHz bandwidth. This combination of features makes the OPA2691 an ideal RGB line driver or single-supply Analog-to-Digital Converter (ADC) input driver. +12V APPLICATIONS q xDSL LINE DRIVER / RECEIVER q MATCHED I/Q CHANNEL AMPLIFIER q BROADBAND VIDEO BUFFERS q HIGH-SPEED IMAGING CHANNELS q PORTABLE INSTRUMENTS q DIFFERENTIAL ADC DRIVERS q ACTIVE FILTERS q WIDEBAND INVERTING SUMMING The OPA2691’s low 5.1mA/ch supply current is precisely trimmed at 25°C.
