CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation

of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

NOTES:

1.

θJA is measured with the component mounted on an evaluation PC board in free air.

2. All voltages with respect to DGND, unless otherwise noted.

3. Assumes all leads soldered or welded to printed circuit board.

Electrical Specifications Test Conditions: V+ = +5V, V- = -5V, VREF = -10V, TA = 25oC, fCLK = 500kHz, Unless Otherwise Noted
