AD7625 Data Sheet ABSOLUTE MAXIMUM RATINGS Table 4. THERMAL RESISTANCE Parameter Rating
θJA is specified for the worst-case conditions, that is, a device Analog Inputs/Outputs soldered in a circuit board for surface-mount packages. IN+, IN− to GND1 −0.3 V to REF + 0.3 V or ±130 mA
Table 5. Thermal Resistance
REF2 to GND −0.3 V to +6 V
Package Type θJA θJC Unit
VCM, CAP2 to GND −0.3 V to +6 V 32-Lead LFCSP_WQ 40 4 °C/W CAP1, REFIN to GND −0.3 V to +2.7 V Supply Voltage
ESD CAUTION
VDD1 −0.3 V to +6 V VDD2, VIO −0.3 V to +3 V Digital Inputs to GND −0.3 V to VIO + 0.3 V Digital Outputs to GND −0.3 V to VIO + 0.3 V Input Current to Any Pin Except Supplies3 ±10 mA Operating Temperature Range −40°C to +85°C (Commercial) Storage Temperature Range −65°C to +150°C Junction Temperature 150°C ESD 1 kV 1 See the Analog Inputs section. 2 Keep CNV+/CNV− low for any external REF voltage > 4.3 V applied to the REF pin. 3 Transient currents of up to 100 mA do not cause SCR latch-up. 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. Rev.
