DIGITAL CHARACTERISTICS, ALL DEVICES

(TA = TMIN to TMAX; VA+, VD+ = 5V ±10%; VA-, VD- = -5V ±10%

29. VA- and VD- can be any value from 0 to +5V for memory retention. Neither VA- nor VD- should be allowed to go

positive. AIN1, AIN2, or VREF must not be greater than VA+ or VD+. This parameter is guaranteed by

characterization.

RECOMMENDED OPERATING CONDITIONS

(AGND, DGND = 0V, see

Note 31)

31. All voltages with respect to ground.

32. The CS5101A and CS5102A can accept input voltages up to the analog supplies (VA+ and VA-). They will produce

an output of all 1s for input above VREF and all 0s for inputs below AGND in unipolar mode, and -VREF in bipolar

mode, with binary coding (CODE = low).
