1 One LSB = VREF/256.
2 The first three codes (0x00, 0x01, 0x10) are excluded from the integral nonlinearity error measurement in single-supply operation 3 V or 5 V.
3 These parameters are guaranteed by design and not subject to production testing.
4 Typical specifications represent average readings measured at 25°C.
5 The SDI/SHDN and A0/SHDN pins have a 30 µA maximum IIL input leakage current.
6 The settling time specification does not apply for negative going transitions within the last three LSBs of ground in single-supply operation.
