TDA7498E Dual Channel Stereo Audio Amplifier is a 15-36V On-board TDA7498E stereo audio amplifier chip. TDA7498E 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 2 x 160W 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 15V – 36 V providing an efficiency of 85%. TDA7498E 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. TDA7498E 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.
This amplifier allows the selection of four fixed gain settings of nominally 23.8 dB, 29.8 dB, 33.3 dB, and 35.8 Db settings via DIP switch selection. The Parallel BTL function in the amplifier performed using the MODE pin. It also has a power indicator to identify the power state of the module. Moreover, it features a thermal overload protection system and features both system shutdown and mute control function.
