AD8532 headphone amplifier circuit schematic
the power supply input signal from the IN jack is fed to a dual stereo volume potentiometer. Because of the required good channel co-ordinate, an ALPS potentiometer was used.

Li-Po Li-ion Battery Charge MCP73831 TP4056 Circuits Li-Po Li-ion Battery Charge MCP73831 TP4056 Circuits During the past year, I replaced a lot of batteries at home with a lot of batteries and replaced them with Li-ion batteries. Lantern radios, Led lantern, Hand broom etc … One of the radio lanterns was a 6v battery and the other one was a 1.5v pen pile. One of the two Li-ion batteries was enough battery power for the Li-ion battery + strike tip serial 1n4007 diode connected to 0.7v voltage loss I made a simple rule with the problem did not make a problem .. Led flashlight 6v battery 1 Li-ion battery is enough Bleached batteries 3 serial Ni Mh batteries connected 3.6v in it 2 Li-ion pliers connected in parallel The mini SOT-23-5 I use for the radio and led flashlight charging circuits is able to power 500mA on the MCP73831 is used with an external circuit element. I used the 5V adapter as the power source for the circuits I put into the devices I also placed the bubble charging circuit in the adapter when the vacuum cleaner is running, if the MCP73831 charging circuit is connected. In the case of MCP73831 R1 resistor is used for current setting, I use 2.2K, 500mA 2K, 240MA 4.2K, 160MA 6.34K, 130MA 7.87K, 100MA 10K capacitors in 10K input and output will be poleless.
