ZHCSQZ9A March 2022 – October 2022 ADS117L11
PRODUCTION DATA
Table 8-16 lists the register map of the ADS117L11. Register data are read or written one register at a time for each read or write operation in a frame. Writing to any register address 4h through Eh results in a conversion restart and loss of synchronization. If the ADC is idle (conversions are stopped), new conversions are not started.
