6.1 Absolute Maximum Ratings

over operating ambient temperature range (unless otherwise noted) (1)
MIN MAX UNIT
Power supply voltage AVDD1 to AVSS –0.3 6.5 V
AVDD2 to AVSS –0.3 6.5
AVSS to DGND –3 0.3
IOVDD to DGND –0.3 6.5
IOVDD to AVSS 8.5
Digital input/output voltage SDO/DRDY, DRDY, START DGND – 0.3 IOVDD + 0.3 V
CS, SCLK, SDI, RESET, CLK DGND – 0.3 6.5
Input current Continuous, any pin except power-supply pins(2) –10 10 mA
Temperature Junction, TJ 150 °C
Storage, Tstg –65 150
(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 briefly operating outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not sustain damage, but it may not be fully functional – this may affect device reliability, functionality, performance, and shorten the device lifetime.
(2) Analog input pins AINP, AINN, REFP, and REFN are diode-clamped to AVDD1 and AVSS. Limit the input current to 10 mA in the event the analog input voltage exceeds AVDD1 + 0.3 V or AVSS – 0.3 V. Digital input pin START and digital output pins SDO/DRDY and DRDY are diode-clamped to IOVDD and DGND. Digital input pins CS, SCLK, SDI, RESET and CLK are diode-clamped to DGND. Limit the input current to 10 mA in the event the digital input voltage exceeds IOVDD + 0.3 V (for effected pins) or exceeds DGND – 0.3 V.
