Product Overview LV47011P: Audio Power Amplifier, Class AB, 4-Channel, 50 W For complete documentation, see the data sheet Product Description The LV47011P is the IC for 4-channel BTL power amplifier that is developed for car audio system. 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. Features • • • • • • High output : PO max = 50W (typical) (VCC = 15.2V, f = 1kHz, RL = 4Ω) High output : PO max = 29W (typical) (VCC = 14.4V, f = 1kHz, THD = 10%, RL = 4Ω) High output : PO max = 22W (typical) (VCC = 14.4V, f = 1kHz, THD = 1%, RL = 4Ω) Built-in muting function Built-in Standby switch Built-in Self-diagnosis function : Signal output in case of output offset detection, shorting to VCC, shorting to ground, and load shorting. • Electric mirror noise decrease • Built-in various protection circuit (shorting to ground, shorting to VCC, load shorting, over voltage and thermal shutdown) End Products Part Electrical Specifications Product Compliance Status Class Output VCC Max Power Typ (V) (W) Output Type LV47011P-E Pb-free Active AB 50 BTL 16 ton Typ (ms) For more information please contact your local sales support at www.onsemi.com Created on: 6/30/2016 THD + N Typ (%) IQ Typ (mA) ISD Typ (nA) Package Type 0.03 200 10000 HZIP-25
