ELECTRICAL CHARACTERISTICS
(Circuit of Figure 1, 4A components from Table 1, V+ = +15V, V
noted.) (Note 1)
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 in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
2
Note 1: For the MAX1714B, AGND and PGND refer to a single pin designated GND.
Note 2: SKIP may be forced below -0.3V, temporarily exceeding the absolute maximum rating, disabling over/undervoltage fault
