ABSOLUTE MAXIMUM RATINGS
Table 8.
Parameter Rating
Power Supply (AVDD, IOVDD) −0.3 V to +3.63 V
Digital Supply (DVDD)
−0.3 V to +1.98 V
Input Current (Except Supply Pins) ±20 mA
Analog Input Voltage (Signal Pins) –0.3 V to AVDD + 0.3 V
Digital Input Voltage (Signal Pins) −0.3 to IOVDD + 0.3 V
Operating Temperature Range (Case) −40°C to +85°C
Storage Temperature Range −65°C to +150°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.
THERMAL RESISTANCE
θ
JA
represents the junction-to-ambient thermal resistance; θ
JC
represents the junction-to-case thermal resistance. Thermal
numbers are simulated on a 4-layer JEDEC PCB with the
exposed pad soldered to the PCB. θ
JC
was simulated at the
exposed pad on the bottom of the package.
