only at the 3 LSBs of this register, so the upper 5 bits
are don’t care bits, which should be set to zero. The
conversion rate tolerance is ±25% at any rate setting.
Valid A/D conversion results for both channels are avail-
able one total conversion time (125ms nominal, 156ms
maximum) after initiating a conversion, whether conver-
sion is initiated through the RUN bit, one-shot com-
mand, or initial power-up. Changing the conversion rate
can also affect the delay until new results are available.

The MAX6648/MAX6692 have a fixed address of 1001
100. The MAX6648/MAX6692 also respond to the
SMBus alert response slave address (see the Alert
Response Address section).
To prevent ambiguous power-supply conditions from
corrupting the data in memory and causing erratic
behavior, a POR voltage detector monitors V
