Original TDA7293 power amplifier HIFI Mono 100W high-power ultra power dual 12 ~ 32V
Output: 100W
The internal use of high-power FET output to meet the enthusiastsboth sound good, but also the desire of large power. Some finished power amplifier internal use of the TDA7293 manifold, with high performance specifications, in the 20Hz ~ 20kHz frequency range, when the supply voltage is 40V, the load is 8, the output power up to 100W.
TDA7293 mono amplifier board
100% full of Jinan original STMicroelectronics monolithic power amplifier chip TDA7293, it is a high-power high-power DM0S high-fidelity power amplifier IC, rated output power of 100W. (Po = 5W, f = IKHz) ± 40V, 8R 100W; ± 45V, 8R 140W; ± 29V, I00W; 0.005%; conversion rate of 15Vus (TDA72M is 10 V / us, the higher the conversion rate, the sound quality of the more hand-rich); input impedance 100KD; frequency response 20Hz-20Kz; work in the Class B state.
Note: must be heat sink! Otherwise, the heart will fry machine!

The TDA7293 internal structure is divided into three levels; the differential input stage consists of bipolar transistors, which push the stage and the power output stage with a field effect transistor. Beautiful advantages, taking into account the advantages of bipolar signal processing circuit and MOS power tube, with low distortion, low noise, high voltage and switch mute, overheating jealousy, short-circuit shovel and other advantages.
TDA7293 Gongzi board wiring instructions:
① The source input (IN) + receives the positive level input of the audio signal, the negative level input of the audio signal
② output speaker (SP); + connected speaker +, - one of the speakers
Remember to use the transformer output of the AC power> curtain with a DC battery or test adapter, otherwise it can not work.
