may cause permanent damage to the device. This is a stress AV rating only; functional operation of the device at these or any DD to AGND −0.3 V to +7 V V other conditions above those indicated in the operational DRIVE to AGND −0.3 V to AVDD + 0.3 V Analog Input Voltage to AGND −0.3 V to AV section of this specification is not implied. Exposure to absolute DD + 0.3 V Digital Input Voltage to AGND −0.3 V to +7 V maximum rating conditions for extended periods may affect Digital Output Voltage to AGND −0.3 V to AV device reliability. DD + 0.3 V REFIN to AGND −0.3 V to AVDD + 0.3 V Input Current to Any Pin Except ±10 mA Supplies1 Operating Temperature Range Commercial (B Version) −40°C to +85°C Storage Temperature Range −65°C to +150°C Automotive Temperature Range −40°C to +125°C Junction Temperature 150°C TSSOP Package, Power Dissipation 450 mW θJA Thermal Impedance 143°C/W (TSSOP) θJC Thermal Impedance 45°C/W (TSSOP) Lead Temperature, Soldering Vapor Phase (60 sec) 215°C Infrared (15 sec) 220°C ESD 1.5 kV 1 Transient currents of up to 100 mA do not cause SCR latch-up.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Rev.
