Data SheetADA4523-1ABSOLUTE MAXIMUM RATINGSTHERMAL RESISTANCETable 3. ParameterRating Thermal performance is directly linked to printed circuit board Supply Voltage, V+ to V− 40 V (PCB) design and operating environment. Careful attention to Input Voltage PCB thermal design is required. +IN and −IN1 V− − 0.3 V to V+ + 0.3 V θJA is the junction to ambient, thermal resistance. SD and SDCOM V− − 0.3 V to V+ + 0.3 V θJC is the junction to case, thermal resistance. For θJC on the Input Current exposed pad package, such as CP-8-29, heat sink applies to the +IN and −IN1 ±10 mA package bottom exposed pad only.

Electrostatic Discharge (ESD) Human Body Model (HBM) 4.0 kV Field Induced Charge Device Model 2.0 kV ESD CAUTION (FICDM)3 1 Limit the input current to less than 10 mA. The input voltage must not exceed 300 mV beyond the power supply. These limits are set by the ESD protection structures at the input pins. 2 A heat sink may be required to keep the junction temperature below the absolute maximum rating when the output is shorted indefinitely. 3 JESD22-C101 (ESD FICDM standard of JEDEC) applicable standard. Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability.
