3 / 62 page ADS4128 www.ti.com SBAS578 – MAY 2012 ABSOLUTE MAXIMUM RATINGS (1) Over operating free-air temperature range, unless otherwise noted. VALUE UNIT AVDD –0.3 to 2.1 V Supply voltage range DRVDD –0.3 to 2.1 V Between AGND and DRGND –0.3 to 0.3 V Between AVDD to DRVDD (when 0 to 2.1 V Voltage AVDD leads DRVDD) Between DRVDD to AVDD (when 0 to 2.1 V DRVDD leads AVDD) 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, TA –40 to +85 °C Temperature range Operating junction, TJ +125 °C Storage, Tstg –65 to +150 °C Electrostatic discharge (ESD) Human body model (HBM) 2 kV ratings (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 and CLKM is less than |0.3 V|. This setting prevents the ESD protection diodes at the clock input pins from turning on.
