TDA7498 High Power Audio Amplifier designed as 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. It comes with a single power supply module designed specifically for home systems and active speaker applications. This low-cost FX-Audio amplifier module based on a TDA7492 amplifier chip allowing it to deliver a power of 2x50W under 8Ω, and this has high efficiency due to its Class D architecture. The module also used in BTL (bridge) mode for the power of 1x100W under 4Ω. The amplifier chip is combined with a heat sink to ensure proper heat dissipation. On the connector site, there is a PH 2.0mm 3 pins connector at the input and screw terminals at the output for the left and right channels.
It supports Wide-range single-supply operation of 10V – 26 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. 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 25.6 dB, 31.6 dB, 35.1 dB and 37.6 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.
