Figure 18. DSP External Clock Mode, 16-Bit Data-Transfer Mode, Conversion Timing (MAX1168 Only)
are shut down on the EOC high-to-low transition. Use
the EOC high-to-low transition as the signal to restart
the external clock (SCLK). To read the entire conver-
sion result, 16 SCLK cycles are needed. Extra clock
pulses, occurring after the conversion result has been
clocked out and prior to the rising edge of CS, cause
the conversion result to be shifted out again. The
MAX1168 internal-clock 16-bit-wide data-transfer mode
requires 32 external clock cycles and 32 internal clock
cycles for completion.

Force CS high after the conversion result is read. For
maximum throughput, force CS low again to initiate the
next conversion immediately after the specified mini-
mum time (t
conversion immediately aborts the conversion and
places the MAX1168 in shutdown.
Scan mode allows multiple channels to be scanned
consecutively or one channel to be scanned eight
times. Scan mode can only be enabled when using the
MAX1168 in internal clock mode. Enable scanning by
