roduct description:
TDA7294 is a class AB monolithic audio power amplifier integrated circuit launched by ST Microelectronics in the 1990s. It sweeps away the previous successful linear set and thick film set of successful release, cold and hard sound. It is widely used in the HiFi field, such as home theater. , Active speakers, high-performance televisions and other fields.
The chip adopts 15-pin dual-line asymmetrical in-line package, the differential input stage is composed of bipolar transistors, and the driving stage and power output stage use DMOS field effect transistor semiconductor technology. This hybrid semiconductor manufacturing process enables TDA7294 to take into account the advantages of bipolar signal processing circuits and MOS power tubes, and has an affinity for playback sound (called "bile power amplifier" by enthusiasts); built-in silent standby function, short-circuit current and overheat protection The function makes its performance more perfect. It can be used in HiFi home audio, active audio, high-performance TV and other fields.
