Absolute Maximum Ratings
RS+ and RS- to GND .. -5V to +70V Continuous Power Dissipation (Multi Layer Board) (TA = RS+ to RS- ... ±2V +70°C, derate 4.8mW/°C above +70°C) ...390mW VDD to GND .. -0.3V to +6V Operating Temperature Range ...-40°C to +125°C REF, CIP, OUT, COP To GND ... -0.3V to VDD + 0.3V Storage Temperature Range ..-65°C to +150°C Continuous Current in REF, CIP ... 5mA Continuous Current in OUT and COP ... 10mA Continuous Current in RS+ and RS- ... 10mA 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.
