† 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 VBB.

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 and VCC and VBB terminals are with respect to ANLG GND. All other voltages are referenced

to DGTL GND unless otherwise noted.

4. Analog inputs signals that exceed 4.2 V peak to peak may contribute to clipping and preclude correct A/D conversion. The digital

code representing values higher than 4.2 V is 10 000 000. For values more negative than 4.2 V, the code is 0000000.
