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.
The VSS terminal is connected to the substrate and must be tied to the most negative supply voltage applied to the device.
NOTES:
1. Output voltages may be shorted to AGND provided that the power dissipation of the package is not exceeded. Typically short circuit
current to AGND is 60 mA.
2. For operation above TA = 75°C, derate linearly at the rate of 2 mW/°C.
