Product Overview LV47022P: Audio Power Amplifier, Class AB, 4-Channel, 48 W For complete documentation, see the data sheet Product Description The LV47022P 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 = 48W (typical) (VCC = 15.2V, f = 1kHz, RL = 4Ω, Max Power) PO max = 28W (typical) (VCC = 14.4V, f = 1kHz, THD = 10%, RL = 4Ω) PO max = 21W (typical) (VCC = 14.4V, f = 1kHz, THD = 1%, RL = 4Ω) • Built-in muting function (pin 22) • Built-in Standby switch (pin 4) • Built-in Self-diagnosis function (pin 25) : Signal output in case of output offset detection, shorting to VCC, shorting to ground, load shorting and over voltage. • Circuit that decrease of Electric mirror noise and GSM noise. • Built-in various protection circuit (shorting to ground, shorting to VCC, load shorting, over voltage and thermal shut down) End Products Part Electrical Specifications Product Compliance Status Class Output VCC Max Power Typ (V) (W) Output Type LV47022P-H Pb-free Active AB 48 BTL 16 ton Typ (ms) Halide free 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 0.02 200 3000 HZIP-25
