Conversion Rate Byte
The conversion rate register (Table 8) programs the time
interval between conversions in free-running autonomous
mode (
RUN
= 0). This variable rate control can be used
to reduce the supply current in portable-equipment appli-
cations. The conversion rate byte
’
s POR state is 07h or
4Hz. The MAX6646/MAX6647/MAX6649 look 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 tol-
erance 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.
