DS1, DS0: The status of the auxiliary data input pins.
These are latched on the first falling edge of the SCLK
signal for the current data register read access.
CID2–0: Channel ID tag (Table 11).
Switching Network
A switching network provides selection between three
fully differential input channels or five pseudo-differen-
tial channels, using AIN6 as a shared common. The
switching network provides two additional fully differen-
tial input channels intended for system calibration,
which may be used as extra fully differential signal
channels. Table 12 shows the channel configurations
available for both operating modes.
Scanning (SCAN-Mode)
To sample and convert the available input channels
sequentially, set the SCAN control bit in the global
setup register. The sequence is determined by DIFF
(fully differential or pseudo-differential) and by the
mode control bits M1 and M0 (Tables 8, 9, 10). With
SCAN set, the device automatically sequences through
each available channel, transmitting a single conver-
sion result before proceeding to the next channel. The
MAX1403 automatically allows sufficient time for each
conversion to fully settle, to ensure optimum resolution
before asserting the data-ready signal and moving to
the next available channel. The scan rate is, therefore,
dependent on the clock bit (CLK), the filter control bits
(FS1, FS0), and the modulator frequency selection bits
(MF1, MF0).
Burn-Out Currents
The input circuitry also provides two “burn-out” cur-
rents. These small currents may be used to test the
integrity of the selected transducer. They can be selec-
tively enabled or disabled by the BOUT bit in the global
setup register.
