PV charger battery circuit 4. I have just finished asembling the bridge version and I am impressed of the quality and the power of this IC! Pinout can vary by different types so allways check from datasheet These are the pins in test circuits I did not get capacitor 0. Thanks for your quick reply, I tried your suggested solution and yes the noise is still present at lower volumes. It is so simple to build that I put it together on a strip board in just a few hours. Yes they are all connected. All the schematic diagrams that I could find seemed to involve lots of hard-to-find components or you had to use it together with a pre-amplifier or some other amplifier stage.

Clearly I need to learn how to read a spec sheet. The design I created was double-sided.

If you have the correct DC voltage in, the circuit is fine as long as the power supply can prove enough current. How can I connect the two inputs to my laptop if I build this on a breadboard? Also, can you help me with the Potentiometer?

Last edited by kak; 26th October at Buy a tablet datashert supply 5V 2A, for fast charging and check current consumption with a multimeter. I enjoy seeing constructed circuits. Please mentioned voltage of capacitors to make the circuit useful for beginners…. Here you build the amplifier. And one more thingi think i should add, I am using USB power supply.

Check the datasheet of your potentiometer to find out the pin configuration, then match that with the diagram above. Check out page 4 on the datasheet. Hey, thanks for the great schematic, I was actually looking to make an audio amp and this one looks awesome! I challenge you to figure it out from the datasheet: I cant seem to find any schematics for this chip.

I wanna datashedt an amplifier use for 6 spkr. Pls help me with the schematic or circuit.

Same thing applies to C7, C12 and C8. Originally Posted by kak I am new to electronics so I have a stupid question.

You can also combine capacitors in parallel or series to get other values: Check the sound level of your music source. Leave datashete Reply Cancel reply Your email address will not be published. If I want to make it Mono, I ignore one of the inputs? FYI, ive lost 4 radios in 3 months through crime and im done dstasheet new radios. Where would I be able to order the 0. You might be able to skip some of them, depending on your power source. Thanks for your effort. For example from Jameco: Im only using my phone as the music player.


Are the potentiometers needs to be a Dual Potentiometer 6 pins or can I use 3 pin potentiometer? Hey, how can I dataeheet the input to the speaker? Do you have any idea?

This will make the sound noisy. Hi Zach, you can schematics in the datasheet: How to test the IC having part no. With this circuit my best guess would be to add a low-pass filter on the input side.

How much voltage rating should have uf capacitor for this circuit.

Hi, this could be because there are only inputs on one channel. Im trying to use them all in my car as a complete built in system, without using a radio that can easily be stolen. Look 3 small pictures for standard pinouts. If the input signal is too high, you will get clipping on the output.
