Battery current problem
Here is the whole schematic of my project. I'm tried to use as few components as possible because there isn't a lot of space in the calculator case but now I'm thinking maybe I'm missing a resistor or a capacitor somewhere...- habafflof

Battery current problem
no, it's all in a reasonable range. The amplifier gets warm when draining 150 mA and I tested it by running it for about 20 minutes and it never got significantly hot so the overheating is not a problem. When both circuits are using the same power source the voltage drop across the mp3...- habafflof

Battery current problem
tanks for the reply. The whole thing is currently on the prototype board. By AAA I did mean the AAA cells but the lifespan of the battery is not really a concern because if I get this to work then I can always get rechargeable batteries. When the circuit is drawing power the voltage drop across...- habafflof

Battery current problem
Greetings... I'm working on a project of putting an mp3 player into a TI-84 calculator. The player itself is a cheap pcb a size of a coin which plays mp3 files stored on an microSD card. The sound output from the player is amplified by an LM386N 8 pin audio amplifier and is played on an 18...- habafflof
