XH-M251 Ultra-High Power Digital Audio Amplifier Module - Dual-Channel 210W+210W Output, Supports Dual AC 12-28V Input, Featuring TDA8954 Chip

TDA8954 is a new high-efficiency Class-D audio power amplifier introduced by NXP Semiconductors, with a typical output power of 2×210w under a 4Ω load. The device uses transformer dual power supply and has a wide power supply range. It can work normally from ±12V to ±28V, and is fully differential input, high power output: when dual AC 28V, RL=4Ω, it can output 2 as a dual-channel amplifier ×210W, due to the BD modulation, the noise is very low in normal operation; there is no "pop" and zero dead time PWM output switch when starting and shutting down; fixed frequency: clock switching frequency can be externally synchronized; high efficiency; static Small current; complete protection functions: overvoltage protection, output current limit.
