ماژول آمپلی فایر دو کاناله(استریو) 100+100 وات TDA7498

TDA7498 high power digital power amplifier board
Features:
1, the board designed anti-back and forth protection, not because of a momentary negation of the power supply and the negative and burned the power amplifier board components
2, the new mute and standby control interface, user-friendly design
3, power input and speaker output terminals using high current terminal blocks
4, high-current inductors shielded to prevent mutual interference
5, very large radiator
7, adjustable voltage output, the original LM317 adjustable voltage regulator independent output circuit, can be used for pre-class MP3 player and other products, external products, then adjust the voltage and then take the other equipment, otherwise it will seriously damage your equipment.
TDA7498 is a dual bridge load (BTL) Class D audio amplifier chip, using a single power supply, with small size, high efficiency, high power and so on. TDA7498 chip with our reasonable layout of the board, and a variety of high-quality components 

Supply voltage: 15V-36V (voltage recommended not to exceed 36V),

the maximum output 100Wx2, heat a small, the efficiency can reach more than 90%.
Operating voltage: 15V-36V current recommended 4A power supply voltage and the size of the relationship between the output ( Note: 4 ohms below the recommended voltage 18-22v, greater than 22V will have a sound .8 European speakers can be used between 12-36v no sound
 
Power output: 100Wx2 (36V 8 ohms) parallel mode (200WX1 4 ohms)
 
Board size about: width 90mm / depth 92mm / height 38mm
The board entry hole spacing is 2.0mm. The output hole spacing is 7.62mm .
