ADCDATA[23:0]: ADC Output Code

The data are post-calibration if the EN_OFFCAL or EN_GAINCAL bits are enabled. The data can be

formatted in 24/32-bit modes depending on the DATA_FORMAT[1:0] settings (see Section 5.6 “ADC

Output Data Format”).

The ADC Channel Data Output registers always contain the most recent A/D conversion data. The

settings). The register is latched at the start of each SPI Read command. The register is double

buffered to avoid data loss. There is a small time delay, tDODR, after each data ready, where the user

has to wait for the data to be available. Otherwise, data corruption can occur (when the internal data

are refreshed).

When IRQ_MODE[1:0] = 1x, this register becomes a 4-bit wide register containing the MDAT output

codes, which are the outputs of the modulator that are represented by four comparator outputs

(COMP[3:0], see Section 5.4.2 “Modulator Output Block”).
