Parameter Rating
may cause permanent damage to the device. This is a stress VDD to AGND −0.3 V to +7 V rating only; functional operation of the device at these or any VDD to DGND −0.3 V to +7 V other conditions above those indicated in the operational Analog Input Voltage to AGND section of this specification is not implied. Exposure to absolute V1P, V1N, V2P, and V2N −6 V to +6 V maximum rating conditions for extended periods may affect Reference Input Voltage to AGND −0.3 V to VDD + 0.3 V device reliability. Digital Input Voltage to DGND −0.3 V to VDD + 0.3 V Digital Output Voltage to DGND −0.3 V to V DD + 0.3 V Operating Temperature Range −40°C to +85°C Storage Temperature Range −65°C to +150°C Junction Temperature 150°C 16-Lead Plastic SOIC, Power Dissipation 350 mW θJA Thermal Impedance1 124.9°C/W Package Temperature Soldering See J-STD-20 1 JEDEC 1S standard (2-layer) board data.
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.
