VREFOUT - The on-chip voltage reference is output from this pin. The voltage reference
has a nominal magnitude of 2.5 V and is reference to the VA- pin on the converter.
VREFIN - The voltage input to this pin establishes the voltage reference for the on-chip
modulator.
IIN+, IIN- - Differential analog input pins for current channel.
VD+ - The positive digital supply is nominally +5 V ±10% relative to DGND.
DGND - The common-mode potential of digital ground must be equal to or above the
common-mode potential of VA-.
VA- - The negative analog supply pin must be at the lowest potential.
VA+ - The positive analog supply is nominally +5 V ±10% relative to VA-.
PFMON - The power fail Monitor pin monitors the analog supply. Typical threshold level
(PMLO) is 2.45 V with respect to the VA- pin. If PFMON voltage threshold is tripped, the
LSD (low-supply detect) bit is set in the Status Register. Once the LSD bit has been set,
it will not be able to be reset until the PFMON voltage increases ~100 mV (typical) above
the PMLO voltage. Therefore, there is hysteresis in the PFMON function.
Reset - When reset is taken low, all internal registers are set to their default states.
NC - No connection. Pin should be left floating.
