6 / 60 page CS4954 CS4955 6 DS278F6 1. CHARACTERISTICS AND SPECIFICATIONS ABSOLUTE MAXIMUM RATINGS AC & DC PARAMETRIC SPECIFICATIONS (AGND,DGND = 0 V, all voltages with respect to 0 V) WARNING: Operating beyond these limits can result in permanent damage to the device. Normal operation is not guaranteed at these extremes. RECOMMENDED Operating Conditions (AGND,DGND = 0 V, all voltages with respect to 0 V.) Note: Operation outside the ranges is not recommended. THERMAL CHARACTERISTICS Note: Four-layer PCB recommended for operation in environments where TA > 70° C. DC CHARACTERISTICS (T A = 25° C; VAA, VDD = 5 V; GNDA, GNDD = 0 V.)
