Description
The TEA2025B is a stereo power amplifier board that can output up to 3 watts + 3 watts into a 1-3 inch 2-10 watt full frequency speaker. It has a matching impedance of 4-16 ohms and is width 39 x depth 52 x height 25mm.
Description
1. All interfaces use screw terminals, so DIY players can easily connect without an electric soldering iron.
2. For the longer working life of the power amplifier chip, and for the best performance of the TEA2025B, we installed a large volume heat sink. If the heat sink is not installed, the power amplifier chip will heat up when working for a long time, when the heat reaches a certain temperature, the output sound will be distorted; when the heat is very serious, the power amplifier chip will burn out!
3. Refer to the TEA2025B official standard circuit design, increase the total volume adjustment knob to facilitate the user to adjust the volume to achieve the best results! The TEA2025B chip has the characteristics of sweet silvery sound, excellent performance, and reliable work. It is loved by a large number of audiophiles. Many major brand audio manufacturers also use this amplifier integrated chip, such as R101V, R101T06, and CJC. -112 and other models use the TEA2025B integrated amplifier!
