VALUE UNIT Supply voltage range, AVDD –0.3 to 2.1 V Supply voltage range, DRVDD –0.3 to 2.1 V Voltage between AGND and DRGND –0.3 to 0.3 V Voltage between AVDD to DRVDD (when AVDD leads DRVDD) 0 to 2.1 V Voltage between DRVDD to AVDD (when DRVDD leads AVDD) 0 to 2.1 V INP, INM –0.3 to minimum (1.9, AVDD + 0.3) V Voltage applied to input pins CLKP, CLKM(2), DFS, OE –0.3 to AVDD + 0.3 V RESET, SCLK, SDATA, SEN –0.3 to 3.9 V Operating free-air temperature range, TA –40 to +85 °C Operating junction temperature range, TJ +125 °C Storage temperature range, Tstg –65 to +150 °C ESD, human body model (HBM) 2 kV (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied. (2) When AVDD is turned off, it is recommended to switch off the input clock (or ensure the voltage on CLKP, CLKM is less than |0.3V|. This prevents the ESD protection diodes at the clock input pins from turning on.
