LOW POWER, 2 MSPS, 10-BIT, A/D CONVERTER WITH 8-CHANNEL MUX
REV. 1.0.0

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. The INL error is the maximum distance
(in LSBs) from the best fit line to any transition voltage.
3 See VIN input equivalent circuit.
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 the XRD87L99 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.
