TDA1308 Audio Power Preamp Preamplifier Board
Magnification adjustable DC 3V-6V
Description:
Notice:The board is not with regulated power supply function, it is better to use regulated power supply or battery-powered, otherwise there may be interference.
Small size design, SMT process, the input and output coupling capacitor using imported brand of non-polar capacitors, Philips original TDA1308 op amp chip. it can work in 3V-6V voltage, to meet the needs of low-voltage power supply applications.
The default is about 5 times magnification, if you want to change you own magnification, operating as follows:
R7, R5 is the magnification setting resistor, the resistance value can choose between 5K-47K, the greater the resistance, the higher the zoom factor. if you want to use plug-in resistors, please remove SMD Resistors, then put the plug-in resistance welding on the reserved pads.
Working Voltage: DC 3V-6V
Board Size: 33mm x 25mm
Packing List:
1pcs x TDA1308 Audio Power Preamplifier Board
