Hi~~I have some questions about THDB_ADA1) what's the ADC output data format? i found the AD9248's datasheet. there were two data output format, offset binary and two's complement. what kind of data format is the THDB_ADA 's output format?? 2) i used logic analyzers to analysis THDB_ADA output 14 bits status, why the bit 9 of ADC always stuck at '1'.
1. It's a hardware pin-strap option, as you can see in the datasheet. If I understand right, it's set to offset binary.2. Incorrect connected LA probe or a hardware fault.
