• Wide-range single-supply operation (14 – 39 V)
• High efficiency (η = 90%)
• Four selectable, fixed gain settings of nominally 25.6 dB, 31.6 dB, 35.1 dB and 37.6 dB
• Applicable speaker impedance: 4/6/8 ohm(8 ohm is the best).
• Differential inputs minimize common-mode noise
• Standby and mute features
• Short-circuit protection

 

Product Description:

TDA7498 High Power Dual Channel Stereo Audio Amplifier is a 14-36 power supply On-board TDA7498 stereo audio amplifier chip. 

TDA7498 digital amplifier board module based on dual BTL class-D audio amplifier with a single power supply module designed specifically for home systems and active speaker applications. It is a linear circuit with a dual-channel, capable of 100w+0W power output, and generates a peak output current of 8A. Thus Dual Channel Stereo Audio Amplifier board module offers very low harmonic distortion and better sound quality. And it can drive 4/6/8 ohm speakers.

It supports Wide-range single-supply operation of 14V – 30 V providing an efficiency of 90%. TDA7498 digital amplifier board module has 5 control buttons. These control buttons are used to change the track or control the volume. 

Meanwhile, the DIP 2 switches button functions as combining the up/down position of each switch you can obtain 4 different filters for the output. TDA7498 High output power digital amplifier features reverse polarity protection. When the heat sink temperature rises to a certain value, the cooling fan will work. It comes in a 36-pin Power SSO package with an exposed pad up (EPU) to facilitate mounting a separate heatsink.
