The fine current adjustment (IADJ) pin of the device is controlled using the potentiometer R17 on the board. By default the potentiometer is set to 0 Ω, which yields the maximum quiescent current for each bias mode. By increasing the resistance of the potentiometer, the quiescent current can be reduced to a desired lowered value at the cost of reduced performance.
