IIN+, IIN- - Differential analog input pins for current channel.

VD+ - The positive digital supply is nominally +5 V ±10% relative to DGND.

DGND - The digital ground is at the same level as 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

is 2.5 V with respect to the VA- pin.

Reset - When reset is taken low, all internal registers are set to their default states.

NC - No connection. Pins should be left floating.

7. SPECIFICATION DEFINITIONS

Full Scale Error

The deviation of the last code transition from the ideal [{(VREFIN) - (VA-)} - 3/2 LSB]. Units

are in LSBs.

Bipolar Offset

The deviation of the mid-scale transition (111...111 to 000...000) from the ideal (1/2 LSB

below the voltage on the VIN- or IIN- pin). Units are in LSBs.
