NOTES
1One LSB = VREF/4096 V for the 12-bit AD7396.
2The first two codes (000H, 001H) are excluded from the linearity error measurement.
3These parameters are guaranteed by design and not subject to production testing.
4Typicals represent average readings measured at +25°C.
5All input control signals are specified with tR = tF = 2 ns (10% to 90% of +3 V) and timed from a voltage level of +1.6 V.
6The settling time specification does not apply for negative going transitions within the last 3 LSBs of ground.
Specifications subject to change without notice.
