Notes:
1
Tester measures code transitions by dithering the voltage of the analog input (V
IN
). The difference between the measured and the
ideal code width (V
REF
/256) is the DNL error (Figure 2.). The INL error is the maximum distance (in LSBs) from the best fit line to
any transition voltage (Figure 3.). Accuracy is a function of the sampling rate (FS).
2
Guaranteed. Not tested.
3
Specified values guarantee functionality. Refer to other parameters for accuracy.
4
--1 dB bandwidth is a measure of performance of the A/D input stage (S/H + amplifier). Refer to other parameters for accuracy within
the specified bandwidth.
5
See V
IN
input equivalent circuit (Figure 4.). Switched capacitor analog input requires driver with low output resistance.
6
All inputs have diodes to DV
DD
and DGND. Input DC currents will not exceed specified limits for any input voltage between
DGND and DV
DD
.

AGND and DGND pins are connected through the silicon substrate. Connect together at the package and to the analog ground plane.

Notes:
1
Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a
stress rating only and functional operation at or above this specification is not implied. Exposure to maximum rating
conditions for extended periods may affect device reliability.
2
Any input pin which can see a value outside the absolute maximum ratings should be protected by Schottky diode clamps
(HP5082-2835) from input pin to the supplies. All inputs have protection diodes which will protect the device from short
transients outside the supplies of less than 100mA for less than 100
m
