Parameter Rating AVDD to AGND 4 V DVDD to DGND 2.2 V PVDD to AGND 2.2 V DVDDIO to DGND 4 V DVDDIO to AVDD −0.3 V to +0.3 V PVDD to DVDD −0.3 V to +0.3 V DVDDIO to PVDD −0.3 V to +2 V DVDDIO to DVDD −0.3 V to +2 V AVDD to PVDD −0.3 V to +2 V AVDD to DVDD −0.3 V to +2 V Digital Inputs Voltage to DGND DGND − 0.3 V to DVDDIO + 0.3 V Digital Outputs Voltage to DGND DGND − 0.3 V to DVDDIO + 0.3 V Analog Inputs to AGND AGND − 0.3 V to AVDD + 0.3 V Maximum Junction Temperature (TJ MAX) 125°C Storage Temperature Range −65°C to +150°C Infrared Reflow Soldering (20 sec) 260°C 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. PACKAGE THERMAL PERFORMANCE To reduce power consumption when using the part the user is advised to turn off any unused ADCs . The junction temperature must always stay below the maximum junction temperature (TJ MAX) of 125°C. This equation shows how to calculate the junction temperature: TJ = TA Max + (θJA × WMax) where: TA Max = 85°C. θJA = 30°C/W. WMax = ((AVDD × IAVDD)+(DVDD × IDVDD)+ (DVDDIO × IDVDDIO) + (PVDD × IPVDD)). THERMAL SPECIFICATIONS Table 6. Thermal Characteristics Symbol Test Conditions Typ Unit Junction-to-Case Thermal Resistance θJC 4-layer PCB with solid ground plane 7 °C/W Junction-to-Ambient Thermal Resistance θJA 4-layer PCB with solid ground plane (still air) 30 °C/W 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. |
