Parameter Rating AVDD1 to GND −0.3 V to +3 V (AVDD2, AVDD3, AVDD4) to GND −0.3 V to +6 V DVDD to GND −0.3 V to +3 V VDRIVE to GND −0.3 V to +3 V VIN+, VIN– to GND −0.3 V to +6 V Digital Input Voltage to GND1 −0.3 V to DVDD + 0.3 V MCLK to MCLKGND −0.3 V to +6 V VREF to GND2 −0.3 V to AVDD4 + 0.3 V AGND to DGND −0.3 V to +0.3 V Input Current to Any Pin Except Supplies3 ±10 mA Operating Temperature Range Commercial −40°C to +85°C Storage Temperature Range −65°C to +150°C Junction Temperature 150°C TQFP_EP Exposed Paddle θJA Thermal Impedance 92.7°C/W θJC Thermal Impedance 5.1°C/W Lead Temperature, Soldering Vapor Phase (60 sec) 215°C Infrared (15 sec) 220°C ESD 600 V 1 Absolute maximum voltage on digital inputs is 3.0 V or DVDD + 0.3 V, whichever is lower. 2 Absolute maximum voltage on VREF input is 6.0 V or AVDD4 + 0.3 V, whichever is lower. 3 Transient currents of up to 200 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. 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. |
