http://www.analog.com/static/imported-f ... AD8016.pdfTwo digitally programmable logic pins, PWDN1 and PWDN0, may be used to select four different bias levels: 100%, 60%, 40%, and 25% of full quiescent power (see Table 7).

The BIAS control pin by itself is a means to continuously adjust the AD8016 internal biasing and, thus, quiescent current IQ. By pulling out a current of 0 μA (or open) to approximately200 μA, the quiescent current can be adjusted from 100% (full on) to a full off condition.
