Data Sheet AD7961 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 GND −0.3 V to VDD1
Table 5. Thermal Resistance
REF1 to GND −0.3 V to +6 V
Package Type θ
VCM to GND −0.3 V to +6 V
JA θJC Unit
REFIN to GND −0.3 V to +6 V 32-Lead LFCSP_VQ 40 4 °C/W Supply Voltages VDD1 −0.3 V to +6 V
ESD CAUTION
VDD2, VIO −0.3 V to +2.1 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 ±10 mA Except Supplies Operating Temperature −40°C to +85°C Range (Commercial) Storage Temperature Range −65°C to +150°C Junction Temperature 150°C ESD Ratings Human Body Model 4 kV Machine Model 200 V Field-Induced Charged- 1.25 kV Device Model 1 Transient currents of up to 100 mA do not cause SCR latch-up. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Rev.
