Hi Ryan, When we use RDATAC and short the input to ground the we are able to get a straight line centred to zero with noise. But when we do same with RDATA we get shifted data. and here are Answers of your Doughts, 1. We are giving Bipolar analog Supply as shown in below image. 2. Yes we are Connecting Ground of PCB with our Function generator's Ground. 3. When JP16 is shorted the voltage at WCT pin is -2.4V and the register configuration are listed below conf|config1 0x01 0xC1 conf|config2 0x02 0x10 conf|config3 0x03 0xFC conf|loff 0x04 0x03 conf|ch1set 0x05 0x10 conf|ch2set 0x06 0x80 conf|ch3set 0x07 0x80 conf|ch4set 0x08 0x80 conf|ch5set 0x09 0x80 conf|ch6set 0x0A 0x80 conf|ch7set 0x0B 0x80 conf|ch8set 0x0C 0x80 conf|rldsensp 0x0D 0xFF conf|rldsensn 0x0E 0xFF conf|loffsensp 0x0F 0xFF conf|loffsensn 0x10 0x02 conf|loffflip 0x11 0x00 conf|gpio 0x14 0x00 conf|pace 0x15 0x00 conf|resp 0x16 0xF0 conf|config4 0x17 0x22 conf|wct1 0x18 0x0A conf|wct2 0x19 0xE3 4. The Amplitude is 500mV, 1Khz freq and Gain is of 1 in both setups.
