Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage param-
eters are absolute voltages referenced to AGND and DGND, all currents are defined positive into any lead. The thermal
resistance and power dissipation ratings are measured under board mounted and still air conditions.

Recommended Component Values
All capacitors are rated 6.3V unless otherwise specified. All resistors are rated 1/16W unless otherwise specified. The
typical connection diagram is shown in figure 3. For proper operation the device should be used with the recommended
components specified below.
