5.1 Absolute Maximum Ratings

over operating ambient temperature range (unless otherwise noted)(1)
MIN MAX UNIT
DVDD to GND –0.3 5.5 V
AVDD to GND –0.3 5.5 V
AINx/GPIOx(2) to GND GND – 0.3 AVDD + 0.3 V
REF to GND GND – 0.3 AVDD + 0.3 V
Digital inputs (CS, SDI, SCLK) to GND GND – 0.3 5.5 V
Input current to any pin except supply pins(3) –10 10 mA
Junction temperature, TJ –40 150 °C
Storage temperature, Tstg –60 150 °C
(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.
(2) AINx/GPIOx refers to AIN0/GPIO0, AIN1/GPIO1, AIN2/GPIO2, AIN3/GPIO3, AIN4/GPIO4, AIN5/GPIO5, AIN6/GPIO6, and AIN7/GPIO7 pins.
(3) Pin current must be limited to 10 mA or less.
