Pch DMOS in the upper side of the output stage and Nch DMOS in the lower side of the output stage are complimentary. High power and high quality sound are realized by that. This IC incorporate various functions (standby switch, muting function, and various protection circuit) necessary for car audio system. Also, it has a self-diagnosis function. Functions • High output : PO max = 41W (typical) (VCC = 15.2V, f = 1kHz, JEITA max, RL = 4Ω) : PO max = 24W (typical) (VCC = 14.4V, f = 1kHz, THD = 10%, RL = 4Ω) : PO max = 17W (typical) (VCC = 14.
