/1024 V for the 10-bit AD7393.
2
The first two codes (0x000, 0x001) are excluded from the linearity error measurement.
3
These parameters are guaranteed by design and not subject to production testing.
4
Typicals represent average readings measured at +25°C.
5
All input control signals are specified with t
R
= t
F
= 2 ns (10% to 90% of 13 V) and timed from a voltage level of 1.6 V.
6
The settling time specification does not apply for negative going transitions within the last 3 LSBs of ground.
