The conversion must complete in some minimum time or
droop on the sample-and-hold capacitors might degrade
conversion results. Use internal clock mode if the clock
period exceeds 10s or if serial-clock interruptions could
cause the conversion interval to exceed 120s.
Internal Clock
In internal clock mode, the MAX1202/MAX1203 generate
their own conversion clock. This frees the P from run-
ning the SAR conversion clock, and allows the con-
version results to be read back at the processor’s
convenience, at any clock rate from zero to 2MHz.
SSTRB goes low at the start of the conversion, then goes
high when the conversion is complete. SSTRB is low for
a maximum of 10s, during which time SCLK should
remain low for best noise performance. An internal regis-
ter stores data while the conversion is in progress. SCLK
clocks the data out at this register at any time after the
conversion is complete. After SSTRB goes high, the next
falling clock edge produces the MSB of the conversion
at DOUT, followed by the remaining bits in MSB-first for-
mat (Figure 9). CS does not need to be held low once a
