Each of the 4 internal op amps is a wideband current feedback amplifier offering very high slew rate intrinsic to that design using low quiescent current levels. Each of the two pair of amplifiers (ports) can also be power optimized to the application using two external quiescent control logic pins. Full power is nominally 27.2mA/port with options of medium power cutback to 23mA/port, a low power condition at 13.5mA/port, and an off state at.
