Differential Analog Output (Output) - The full-scale differential analog output level is specified in

the Analog Characteristics specification table.

Each positive leg of the differential outputs may also be used single-ended.

29,30

49,50 Test In (Input) - This pin is an input used for test purposes. It must be tied to ground for normal

51,52 operation.

31,32 Test Out (Output) - This pin is an output used for test purposes only. It must not be connected to

33,34 any external trace or other connection.

35,48 Analog Ground (Input) -

36 Quiescent Voltage (Output) - Filter connection for internal quiescent reference voltage.

37,46 Analog Power (Input) - Positive power supply for the analog section.

39,38

41,40 Differential Analog Input (Input) - Signals are presented differentially to the delta-sigma modula-

43,42 tors. The full-scale input level is specified in the Analog Characteristics specification table.

45,44

Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling cir-

cuits.
