ProductDescription : 1. To strengthen we use , an OP amplifier designed to perform this delicate task.
2
3. You can set a reinforcement from 25x to 125x, read with ADC microcontroller. The output is next to the varnish, so if the sounds loudly, the output may increase to 5VPP.
4. To get the best performance, use the available "quietest" delivery. The wave of sound will come out of Pinezj. The output will have a DC VCC/2 deviation, so when it is perfectly quiet, the voltage will be a solid VCC/2 volty (DC is coupled). If the used audio equipment requires a conjugated sound with alternating current, place a 100UF capacitor between the output pin and the input of the devices. If you connect with an audio amplifier that has input data or contains separation capacitors, the 100UF cap is not required.
5. Using it is simple: connect GND to the ground, VCC to 2.4-5VDC.
6. The output pin is not designed to drive speakers or anything, except the smallest earphones, you will need an audio amplifier (such as our 3.7W stereo amplifier) ​​if you want to connect the amplifier directly to the speakers.
