  • AD828/TDA1308 Preamplifier Audio Amplifier Module

     

    Product Information:

     

    ● Small volume design, full chip process, imported non-polar brand capacitors are used as input and output coupling capacitors, and fever grade AD828/TDA1308 chips are used as operational amplifiers.

     

    ● If you feel that the default magnification is inappropriate, you can change the magnification yourself, as follows:

    Adjustment of magnification: R7 and R5 are the set resistances for magnification (the default magnification for shipment is about 5 times, and the magnification can be changed according to your own needs. The resistance can be selected from 5k-47k. The greater the resistance, the higher the magnification. If plug-in resistors are used, the original patch resistors can be removed, and the plug-in resistors can be soldered on the reserved pads at both ends of the placement)

     

    ● Plate size: 33mm * 25mm

     

    ● Working voltage: DC 5v-15v

     

    ● Note: The board is not provided with regulated power supply, so it is better to use regulated power supply or battery power supply during installation, otherwise there may be interference.
