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 Figure 4.). 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 MP8799 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 100µs.

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