Permanent damage to the device may be caused by continuously operating at or beyond these limits. Device functional operating limits and guaranteed performance specifications are given under Electrical Characteristics at the test conditions specified. ESD Sensitive Device. This device is manufactured on a CMOS process. It is therefore generically susceptible to damage from excessive static voltages. Proper ESD precautions must be taken during handling and storage of this device. Cirrus Logic tests its package types according to IPC/JEDEC J-STD-020 for Moisture Sensitivity to determine acceptable storage conditions prior to surface mount assembly. These levels are: MSL1 = unlimited floor life at <30 C / 85% Relative Humidity. Not normally stored in moisture barrier bag. MSL2 = out of bag storage for 1 year at <30 C / 60% Relative Humidity. Supplied in moisture barrier bag. MSL3 = out of bag storage for 168 hours at <30 C / 60% Relative Humidity. Supplied in moisture barrier bag. The Moisture Sensitivity Level for each package type is specified in Ordering Information. CONDITION MIN MAX Analogue supply voltage: AVDD1-2, LDO1VDD-LDO2VDD, DBVDD GND - 0.3V GND + 5V Analogue grounds: AGND1-3, LDO1GND-LDO2VDD, DBGND GND - 0.3V GND + 0.3V Analogue inputs (IN1-6) GND - 0.3V AVDD + 0.3V Other Analogue pins GND - 0.3V AVDD + 0.3V Digital I/O pins GND - 0.3V AVDD + 0.3V Operating temperature range: TA -40C +85C Storage temperature prior to soldering 30C max / 85% RH max Storage temperature after soldering -65C +150C Notes: 1. GND denotes the voltage of any ground pin. 2. AGND, LDOGND and DBGND pins are intended to be operated at the same potential. Differential voltages between these pins will degrade performance. RECOMMENDED OPERATING CONDITIONS CONDITION SYMBOL MIN TYP MAX UNITS Operating temperature range TA -40 85 C Analogue Supply voltage AVDD1-2 LDO1VDD- LDO2VDD DBVDD 2.97 3.3 3.63 V |
