NOTES
1
One LSB = V
/4096 V for the 12-bit AD7390.
2
The first two codes (000
, 001
) 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
=
t
= 2 ns (10% to 90% of 3 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.
Specifications subject to change without notice.
