† _{Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and}
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: Voltages applied to DVDD1 and DVDD2 are measured with respect to the DGND terminal. AVDD is measured with respect to the AGND
terminal. For the following specifications, unless otherwise noted, AGND and DGND are tied togather (and represent 0 volts) and are
referred to simply as GND. When the voltages applied to DVDD1, DVDD2, and AVDD are equal, they are referred to simply as VDD, unless
otherwise noted.
