TDA7498 100W+100W High-Power Digital Amplifier Board Finished Grade Fever Class D HIFI

TDA7498 100W+100W High-Power Digital Amplifier Board Finished Grade Fever Class D HIFI

Description:
- A version of the board and the B version following differences:
- B Version : price $37.98 is standard version . Default shipping B version board, For A version board please contact the seller to change the price .
- A version : Price $38.98,include original LM317 adjustable voltage regulator with independent output circuits can be used for pre-use products such as MP3 players , external product when the first good voltage regulation followed by other devices , otherwise it will seriously damage
- Operating voltage: 15V-34V DC supply voltage over current proposal 4A power supply voltage and the output size relationship
- Power Output : 100Wx2 (34V 8 ohms) in parallel mode (200WX1 4 Euro )
- And connection method , please refer to the diagram , you need to pick your own , oh :
- Board size is about: width 81mm / depth 100mm / 23mm high
- Board input hole spacing is 2.0mm. The output is a 5mm hole spacing.
- The board is a good product welding test plate , just plug in the power , speakers, and audio can be used. 8 ohm load recommended supply voltage is within 34V, 4 ohm load within the recommended supply voltage 30V, 4 European parallel mode 34V supply voltage can not pick the wrong sign of another power , otherwise the chip may be damaged .
- Give you about the difference between the lower TDA7498 and TDA7498L
- TDA7498L 80W X2 TDA7498 100W X2 thrust power to be bigger and more can strengthen the connection to mono for 200W 4 Ohms Output
- TDA7498IC price to be more expensive
- TDA7498 is a dual bridge connected load (BTL) class-D audio amplifier chip , using a single power supply , with small size, high efficiency , high power characteristics. TDA7498 chip with a reasonable layout of our fine board , as well as with a variety of high-quality components, such as : custom designed digital amplifier dedicated high-current inductors , Philips , nichicon, high temperature and high frequency low impedance capacitor fever , Original Samsung SMD chip devices, etc. and so on. This amplifier circuit board is simple , reliable work. Supply voltage 15V-34V ( voltage recommended not to exceed 34V), the maximum output 100Wx2, heat a small, efficiency can reach 90 %. You can use switching power supply, also suitable for battery or battery-powered portable electronics. TDA7498 amplifier board compact, use and installation are very flexible and convenient to use genuine components using all devices capable of long-term stability.
