Monolithic Linear IC

Four-Channel 45 W BTL Car Audio

Power Amplifier

LA47536

Overview

The LA47536 is a 4-channel BTL power amplifier IC developed for use in car audio systems. The output stage features

a pure complimentary structure that uses V-pnp transistors on the high side and npn transistors on the low side to

provide high power and superb audio quality.

The LA47536 includes almost all the functions required for car audio use, including a standby switch, a muting

function, and each protection circuit. It also provides a self-diagnosis function (output offset detection).

Functions and Features

• Voltage gain: 32 dB

• High output power

— Pomax(1) = 45 W (typical)

(At V = 14.4 V, f = 1 kHz, Vi = 2.5 Vrms, RL = 4 Ω)

— Pomax(2) = 40 W (typical)

(At V = 13.7 V, f = 1 kHz, Vi = 2.5 Vrms, RL = 4 Ω)

— Po = 28 W (typical)

(At V = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω)

• Muting function (pin 22)

• Standby switch (pin 4)

• Built-in various protection circuits

— Output pin-to-V short

— Output pin-to-GND short

— Load short

— Over voltage

— Thermal shut down

• Self-diagnosis function that detects the output offset (pin 25)

• Output offset detection on/off switch (pin 1)
