Description:
- TDA7850 is a high-quality hi fi car audio power amplifier IC of ST company. It adopts single power supply 12v-14.4v power supply, MOSFET amplified output, 4 x 50W hifi power amplifier, with small distortion, low noise, strong anti-interference ability, output short circuit and temperature protection, especially in terms of power consumption. It has outstanding performance, ultra-low power consumption, stable operation and good sound quality. HiFi concept design is the best choice for car audio upgrade and DIY 4-channel power amplifier. It can be used for multi-channel production. With the super good noise reduction chip ba3121, the common ground noise is effectively eliminated
Features:
1: Adopts Nichicon gold word audio special capacitor, black diamond, Elna and other electrodeless coupling capacitors. Other bypass filter small blue Elna capacitors are also Elna capacitors. This high-quality capacitor is used exclusively.
2: Up to 10000uf large electrolysis is adopted, and the bass is more low. LC large magnetic ring filter is adopted to better filter all kinds of interference and power supply noise. Samsung chip high-precision capacitor.
3: The humanized design. It is debugged and optimized on the official line of the original factory. The reasonable design and fever components make it give full play to its maximum performance.
4: Using LC filter, the power supply is purer, the ripple is smaller and the interference is smaller
5: Large magnetic loop inductive filtering. Noise reduction with ba3121 isolation
5: 4 inputs / 4 outputs
6: DC 12V power supply or 12V automobile power supply.
Note:
The installation position of LED power indicator is reserved on this board. If it is necessary to install LDE power indicator, please explain, and an additional material fee and production cost of 1 yuan shall be charged. Because this board is made in batch, it needs to be installed separately.
Relevant parameters are as follows:
High output power capability:
4 x 50W / 4 Ω max. (maximum power / horn load of 4 Ω)
