Data Sheet
- Detailed Description
Figure 23. Detailed Serial Interface Timing Waveforms
The external serial clock shifts data in and out of the devices and drives the analog-to-digital conversion steps. Two
clock periods after the last bit of the control byte is written the output pin SSTRB pulses high for one clock period.
The serial data is shifted out at DOUT on each of the next 12 SCLK rising edges (see
Figure 21 on page 17
).
Pins SSTRB and DOUT go into a high-impedance state when CSN goes high. The conversion must complete in 120μs
or less, or consequently, droop on the sample-and-hold capacitors may degrade conversion results.
Figure 23
shows
detailed serial-interface timing waveforms.
Transfer Functions
Output coding and transfer function depend on the control register bits
MODE (page 15)
and
RANGE (page 15)
.
