NOTES:
1
Guaranteed. Not tested.
2
Tester measures code transition voltages by dithering the voltage of the analog input (VIN). The difference between the measured
code width and the ideal value (VREF/1024) is the DNL error (see NO TAG). The INL error is the maximum distance (in LSBs) from
the best fit line to any transition voltage (
See Figure 7.).
3
See VIN input equivalent circuit (see Figure 9.).
4
Clock specification to meet aperture specification (tAP). Actual rise/fall time can be less stringent with no loss of accuracy.
5
Specified values guarantee functional device. Refer to other parameters for accuracy.
6
System can clock MP8798 with any duty cycle as long as all timing conditions are met.
7
Input range where input is converted correctly into binary code. Input voltage outside specified range converts to zero or full scale
output.
8
DVDD and AVDD are connected through the silicon substrate. Connect together at the package.

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
µs.
3
VDD refers to AVDD and DVDD. GND refers to AGND and DGND.
