Note

1:

RLAD (RF+RG in Figure 4-1) connects VREF, VOUT and the inverting input of the internal amplifier. The MCP6S92 has

VREF tied internally to VSS, so VSS is coupled to the internal amplifier and the PSRR spec describes PSRR+ only. It is

recommended that the MCP6S92’s VSS pin be tied directly to ground to avoid noise problems.

2:

The MCP6S92’s VIVR and VIVR_REF are not tested in production; they are set by design and characterization.

3:

IQ includes current in RLAD (typically 60 µA at VOUT = 0.3V). Both IQ and IQ_SHDN exclude digital switching currents.
