Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These
are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated
under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for
extended periods may affect device reliability.

1. Voltage values for DGTL VDD are with respect to DGTL GND, voltage values for DAC VDD are with respect
to DAC GND, and voltage values for ADC VDD are with respect to ADC GND. For the subsequent electrical,
operating, and timing specifications, the symbol VDD denotes all positive supplies. DAC GND, ADC GND,
DGTL GND, and SUBS are at 0 V unless otherwise specified.
2. To avoid possible damage to these CMOS devices and associated operating parameters, the sequence
below should be followed when applying power:
(1) Connect SUBS, DGTL GND, ADC GND, and DAC GND to ground.
(2) Connect voltages ADC VDD,and DAC VDD.
(3) Connect voltage DGTL VDD.
(4) Connect the input signals.
When removing power, follow the steps above in reverse order.
