Table 14.
A data valid output clock signal (DAV) can be used to capture the data delivered by the
ADC1210S. Detailed timing diagrams for CMOS and LVDS DDR modes are shown in
Figure 4
An out-of-range signal is provided on pin OTR. The latency of OTR is fourteen clock
cycles. The OTR response can be speeded up by enabling Fast OTR (bit FASTOTR = 1;
see
Fast OTR detection threshold (below full-scale) can be programmed via bits
FASTOTR_DET[2:0].
Table 15.
By default, the ADC1210S delivers output code that corresponds to the analog input.
However it is possible to add a digital offset to the output code via the SPI (bits
DIG_OFFSET[5:0]; see
For test purposes, the ADC1210S can be configured to transmit one of a number of
predefined test patterns (via bits TESTPAT_SEL[2:0]; see
can be defined by the user (TESTPAT_USER; see
when TESTPAT_SEL[2:0] = 101. The selected test pattern will be transmitted regardless
of the analog input.
