Data SheetAD5749ABSOLUTE MAXIMUM RATINGS TA = 25°C, unless otherwise noted. Transient currents of up to Stresses at or above those listed under Absolute Maximum 100 mA do not cause SCR latch-up. Ratings may cause permanent damage to the product. This is a Table 4. stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational Parameter Rating section of this specification is not implied. Operation beyond AVDD to GND −0.3 V to +58 V the maximum operating conditions for extended periods may DVCC to GND −0.3 V to +7 V affect product reliability.
