10.8.2.3
CPhase controls which internal clock phase the compar-
ator data is latched on.
CLatch controls whether the latch is active or if it is
always transparent.
CompCap controls whether the compensation capacitor
is switched in or not in the op-amp. By not switching in
the compensation capacitance, a much faster response

can be obtained if the amplifier is being used as a com-
parator.
TestMux – selects block bypass mode for testing and
characterization purposes.
Power – encoding for selecting 1 of 4 power levels. The
blocks always power up in the off state.
