Product Overview

Description

1. This board is designed with anti-reverse protection, which will not burn the components of the power amplifier board due to the inadvertent connection of the positive and negative poles of the reverse power supply. 2. Added mute and standby control interface, humanized design, so that DIY enthusiasts can install applications more reasonably 3. The power input and speaker output end use high-current terminal blocks. Thicker wires can be used to ensure high power requirements. 4. Shield large current inductors to prevent mutual interference and better prevent external magnetic field interference 5. Ultra-large heat sink to ensure high power output can better dissipate the high temperature generated by the chip, while ensuring performance, better protecting the chip's service life 6, the original authentic Philips BC037 electrolytic capacitors, no matter the performance, sound quality, workmanship, etc. 7, adjustable voltage output, original LM317 adjustable voltage regulator independent output circuit, can be used for pre-stage MP3 players and other products, when external products adjust the voltage before connecting other equipment, otherwise it will seriously damage your equipment. TDA7498 is a dual bridge load (BTL) Class D audio amplifier chip. It uses a single power supply and has the characteristics of small size, high efficiency and high power. The TDA7498 chip matches the reasonable and exquisite layout of our board and the matching of various high-quality components, such as: specially customized high-current shielded inductors for digital power amplifiers, Philips, nichicon, high-frequency high-temperature low-resistance fever capacitors, original Samsung SMD chip devices and many more. The circuit of this power amplifier board is simple and reliable. The power supply voltage is 15V-36V (the voltage is recommended not to exceed 36V), the maximum output is 100Wx2, the heat generation is small, and the efficiency can reach more than 90%. It can be powered by a switching power supply, and is also suitable for battery- or battery-powered portable electronic products. The TDA7498 power amplifier board is small in size, and it is very flexible and convenient to use and install. All the components used are genuine devices, which can be used for long-term stable work. Working voltage: 15V-36V. It is recommended that the size of the power supply voltage above 4A is related to the output. (Note: The recommended voltage for speakers below 4 ohms is 18-22v, and there will be sound interruption if it is greater than 22V. 8-ohm speakers can be used without interruption between 12-36v. .4 Euro speaker, friends who require high volume without interruption can choose to buy TDA7498E chip 160W + 160W, 12-36V without interruption.
Power output: 100Wx2 (36V 8 ohms) Parallel mode (200WX1 4 ohms) Board size: 90mm wide / 92mm deep / 38mm high The input hole spacing of the board is 2.0mm. The output hole pitch is 7.62mm. The boards are all finished boards tested by welding. You only need to connect the power supply, speakers and sound source to use. 8 ohm load is recommended to supply voltage within 35V, 4 ohm load is recommended to supply voltage within 24V, 4 ohm parallel mode power supply voltage can be designed with 36V anti-reverse protection, will not burn the power amplifier board components by connecting the positive and negative poles .
Tips
Because the power amplifier board is an accessory, you need to connect it yourself before you can use it. The power supply is reversed, and the high voltage will cause fatal damage to the chip.
The following are the measured parameters.
