TDA8920BTH Philips high-efficiency Class D digital audio amplifiers. IC used HSOP24 power package with low power consumption and static current. As the internal tube is a MOS output, so the sound quality has a good performance.
Deep powerful bass and good flexibility. Alto honest warm, bright and clear treble.
1 with two original TDA8920BTH
2 main electrolytic capacitor using ELNA brand, size 4 * 4700UF/35VUF, 8A and above the use of flat bridge rectifier, ensure strong support for a steady stream of power.
3 resistors use metal rings resistance, the main circuit employs a precision of ± 1% metal film resistors rings, ensure the machine a good signal to noise ratio.
4. PCB using 1.6mm thick double-sided sheet, 2.0 oz copper thickness, HASL whole process to ensure the size of the current through the good performance. First-class quality of the PCB.
PCB size is: 13.5CM * 9CM
