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.

Differential

Current Inputs

15,16

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

Power Supply Connections

Positive

Digital Supply

3

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

Digital Ground

4

DGND - The digital ground is at the same level as VA-.

Negative

Analog Supply

13

VA- - The negative analog supply pin must be at the lowest potential.

Positive

Analog Supply

14

VA+ - The positive analog supply is nominally +5 V ±10% relative to VA-.

Power Fail Monitor

17

PFMON - The power fail Monitor pin monitors the analog supply. Typical threshold level

is 2.5 V with respect to the VA- pin.

RESET

19

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

Other

No Connection

8,18

NC - No connection. Pins should be left floating.
