Other Parts Discussed in Thread: THS4551, ADS127L01
Hello. I am trying to understand how the ADS127L01EVM has implemented the THS4551, and in the user manual the schematic shows VOCM as an input (Figure 32). I do not see anywhere on the schematic that VOCM is generated. VOCM measures ~1.5 V at TP18, so it is about half of AVDD_3V as expected. How is VOCM generated on the ADS127L01EVM? Is there a voltage divider or is there another regulator that is not shown on the schematic? Thanks!
