† 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 value is with respect to GND.

NOTES:

2. To avoid possible damage to these CMOS devices and resulting reliability problems, the power-up sequence detailed in the system

reliability features paragraph should be followed.

3. Voltages at analog inputs, outputs, and VCC are with respect to GND.

4. RL and CL should not be applied simultaneously.
