Note 1:
Note 2:
Note 3:
Limits are guaranteed by 100% testing, sampling, or correlation with worst-case test conditions.
Supply current and analog ground current are specified with the digital inputs stable and no load on V
OUT
.
In unipolar operation with V
ZS
and AGND tied together, digital codes that represent an analog value of less than 100mV from AGND should be avoided.
