Product Description

TDA7850 4X50W HiFi Car Audio Power Amplifier Board Module BA3121 Denoiser DC 12V DC 14.4V with Time delay ACC interface


TDA7850 car car power amplifier with ACC function control (sound quality enhanced version)

TDA7850 is ST's high-quality Hi-Fi car audio amplifier IC, single power supply 12V - 14.4V power supply, MOSFET amplified output, 4 x 50W HiFi amplifier, small distortion, low noise, anti-interference ability, with output short circuit and temperature protection , Especially in terms of power performance is particularly prominent, low power, stable, sound quality] good. For car audio upgrade and DIY 4-channel amplifier the most good choice.

HIFI concept design, can be used for multi-channel production, with a good performance noise reduction chip BA3121, effectively eliminating the total noise, TDA7850 and BA3121 can be considered a pair. With this piece of TDA7850, no longer have trouble to install a noise reduction circuit! This is a valuable design Oh!


Related parameters are as follows:

High output power capability:

4 x 50W / 4Ωmax (high power / 4 ohm speaker load)

4 x 30W / 4Ω14.4V, 1KHz, (10% distortion power / 14V voltage measurement, 1KHz signal / 4 ohm speaker load)

4 x 80W / 2Ωmax. (High power / 2 ohne speaker load)

4 x 55W / 2Ω14.4V, 1KHz, (10% distortion power / 14V voltage measurement, 1KHz signal / 2 ohm speaker load)



Appications:


Regardless of car computer, MP3, GPS, mobile phones, CD and other car audio and video equipment can be simple and easy to connect, so you can listen to all kinds of wonderful music, days Lai sound, all the way go hand in hand.


Board size: length 65mm wide 50mm high 46mm


ACC function control introduction

(ST-BY) is the ACC control terminal, controlled by the ACC control signal amplifier work and standby state.

Standby current is about 12 milliamperes, basically no electricity. Through the ACC when the power amplifier board extension] when the function (extension) when about 3 seconds) play a slow start to prevent the impact of sound.

Boot order requirements, DVD boot and then power amplifier is the right boot.

Now found that most of the navigation are Andrews system, the boot is generally much slower than the conventional machine, then the power may be extended] slow start 3 seconds boot is not enough, the host is too slow to start the recommended amplifier board ACC control And the MUTE link of the original car amplifier module.
