NOTES
1One LSB = V
REF/256.
2The first three codes (00
H, 01H, 10H) are excluded from the integral nonlinearity error measurement in single supply operation +3 V or +5 V.
3These parameters are guaranteed by design and not subject to production testing.
4Typicals represent average readings measured at +25
°C.
5SDI/SHDN and A0/SHDN pins have 30
µA maximum I
IL input leakage current.
6The settling time specification does not apply for negative going transitions within the last 3 LSBs of ground in single supply operation.
Specifications subject to change without notice.
