1 One LSB = VREF/4096 V for the 12-bit AD7392.
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 tR = tF = 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.
