The TDA892x Audio Amplifier Module is a Class D Stereo Audio Amplifier based on TDA892x series Class D Audio Power Amplifier made by NXP (Philips) Company. The default Power IC for this module is TDA8920TH. Other IC's can choose. The output power start at 2x20W for TDA8922TH IC, 2x70W for TDA8920TH IC, 2x90W for TDA8924TH IC and up to 2x120W for TDA8950TH IC. The amplifier module can be used in Stereo Single Ended Mode or BTL mode without any modifications. This amplifier is a complete solution for middle and above middle power levels, it only requires a power transformer, wires, signal and speaker connectors and housing. The design of this board is in accordance with the manufacturer datasheet and recommendations, as well as the reference designs. Furthermore, some improvements has been made to make the board more compact and suitable to use both in new designs, in which the user will adopt the preferred housing, input stages and power supply, and can be used also as a drop-in replacement for existing audio amplifiers, which already have housing, transformer, and input stage. The size of the PCB is 58x68mm. Heatsink size is 58x30x70mm.
