In this mode, the noninverting input is sourced from the external OPAx_INx+ input (PSEL = 0x1 or 0x2). The NSEL bits must select RTAP as the inverting input for the amplifier (NSEL = 0x4) and from the MSEL bits a bias is chosen from either ground or the 12-bit buffered DAC (DAC_OUT).
Figure 14-3 shows an example of the OPA in noninverting PGA mode.
