The ADC128D818 is a 12 bit A/D convertor.The datasheet insists that output of the device is mapped in 16 bit register (two 8 bits registers).Can you let me know how 12bits data are mapped on to 16 bit registerIs the 12 bits data is mapped MSB stuffing or LSB bit stuffing, like “0000b+12 bit data” or “12 bit data + 0000b”?
When 2.5V input is applied to the device, the readout data was 0xF9A0”. The data seemed to be LSB stuffing.
I confirmed that the data are filled from MSB like “12 bit data + 0000b”.
In reply to Kikuo Mita:
This should have been specified in the user guide. We ran into this as well and it threw us off for awhile.
