ELECTRICAL CHARACTERISTICS

(VDD = 11.4V to 16.5V, VSS = -11.4V to -16.5V, AGNDA = AGNDB = DGND = 0V, VREFA and VREFB = +10V, RL = 2kΩ,

CL = 100pF, VOUT_ connected to RFB_, TA = TMIN to TMAX, unless otherwise noted.)

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.

REFERENCE INPUTS (VREFA, VREFB)

Note 1: If VSS is open-circuited with VDD and either AGND applied, the VSS pin will float positive, exceeding the Absolute Maximum Ratings.

A Schottky diode connected between VSS and GND ensures the maximum ratings will not be exceeded.
