Product Summary
The OPA2681U is a dual wideband, current feedback operational amplifier with disable. The OPA2681U sets a new level of performance for broadband dual current feedback op amps. Operating on a very low 6mA/ch supply current, the OPA2681U 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 OPA2681U can deliver a 1V to 4V output swing with over 100mA drive current and 150MHz bandwidth. This combination of features makes the OPA2681U an ideal RGB line driver or single supply ADC input driver. The applications of the OPA2681U include xdsl line driver, matched i/q channel amplifier, broadband video buffers, high speed imaging channels, portable instruments, differential adc drivers, active filters and wideband inverting summing.
