The MAX1115/MAX1116 perform conversions by using
an internal clock. This frees the µP from the burden of
running the SAR conversion clock, and allows the con-
version results to be read back at the µP’s convenience
at any clock rate up to 5MHz.

The acquisition interval begins with the falling edge of
CNVST. CNVST can idle between conversions in either
a high or low state. If idled in a low state, CNVST must
be brought high for at least 50ns, then brought low to
initiate a conversion. To select V
the CNVST pin must be brought high and low for a
second time (Figures 6c and 6d).
