LA47536
Monolithic Linear IC
Four-Channel 45 W BTL Car Audio
Power Amplifier
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 VCC = 14.4 V, f = 1 kHz, Vi = 2.5 Vrms, RL = 4 Ω)
— Pomax(2) = 40 W (typical)
(At VCC = 13.7 V, f = 1 kHz, Vi = 2.5 Vrms, RL = 4 Ω)
— Po = 28 W (typical)
(At VCC = 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-VCC 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)
