LA datasheet For a better experience, please enable JavaScript in your browser before proceeding. Its max capacity is 19W into a 4 Ohm speaker. Page 1 of Stereo use Sample Application Circuit 2. Thread starter learning Start date Dec 16, I have a double ic board it was working fine but one day it stop working when I connect power supply to the board the supply wire get hot please tell me the solution of the problem. Built-in 2 channels dual enabling use in stereo and bridge amplifier applications.

It also sounds wonderful. First Prev 2 of 2 Go to page. If you want to learn PCB design then look at the recommended designs for the chips you are using and try to understand why the layouts are done in that particular way.

Features Built-in 2 channels dual enabling use in la datasheet and bridge amplifier applications. You must log in or register to reply here. Use a capacitor in parallel of rectifier and connect an extra wire to the ground of your circuit. If datasheef of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected.

When la datasheet the board, refer to the sample printed circuit pattern and be careful that no feedback loop is formed between ratasheet and output. My home stereo and car audio system have their tone controls set to FLAT. Use a 12 V DC power supply able to deliver at least 3A current. I la datasheet dwtasheet printed wiring for your outputs is too narrow and might burn la datasheet when 1A to 2A flows in them.

Posted on June 21, la datasheet Love. Nearly all my audio circuits are in a plastic la datasheet and are not connected to an earth ground. Electro Tech is an online community with overmembers dataseet enjoy datasheeg about and building electronic circuits, projects and gadgets.

The AD provides low noise 2. Carefully understand the specifications of LA given below before proceeding Use a 4 Ohm speaker as load. The datasheet for the obsolete LA amplifier IC shows that its input resistance is 80k ohms so datasheeh 10k or 20k logarithmic audio taper volume control should be used.

LA IC has ripple rejection upto 46dB. The Ratasheet has built in thermal, over voltage and short circuit protection. Log in or Sign up. Related Posts.
