† _{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.
NOTE 1: Voltage values for maximum ratings are with respect to V_BB.

NOTES:
2. To avoid possible damage to these CMOS devices and resulting reliability problems, the power-up procedure described in the device
power-up sequence paragraphs later in this document should be followed.
3. Voltages at analog inputs and outputs, V_CC and V_BB, are with respect to ANLG GND. All other voltages are referenced to
DGTL GND unless otherwise noted.
