The AMPLIFIER FROM the isd1820 CHIP is super Simple and super Sensitive

How do I make a good loud and very sensitive amplifier out of a chip ? It's very simple! 

Here even to think particularly not need to (but that Spain) - being chip ISD1820, couple of capacitors, one resistor and all!  Well, of course, the wires, speaker And Batteries do not forget-they will be useful.

To be honest, I just did not expect such a wonderful effect - the sensitivity of the amplifier is just off the scale, the volume even from 3-volt batteries is amazing. I can compare with TDA and Uskami, so there is much more fuss, and the results are about the same, well, with a body kit, there is almost no hassle.

I had to pochudit a little with the resistance setting the frequency of the clock generator of the chip itself - it strongly depends on the volume and sound quality, but my version of 20 kom with 3V power supply I think will be useful to many.

Schematics as always attached-use. For simplicity, do not swear, here of course it was possible and the body kit and feedbacks and stabilizers prisobachit, but, as they say - if it works well, then why spoil it ? =)
