Product Descriptions

HT560 is an efficient I2S input D-class stereo audio power amplifier. HT560 can be controlled by hardware or software I2C. In BTL mode, it can provide 2 * 30W/8 Ω power output; In PBTL mode, it can provide a 75W/4 Ω power output.

The HT560 has an over temperature limiting function. When the internal temperature of the chip reaches the over temperature limiting point, the HT560 automatically reduces the gain, allowing its IC to play continuously without interruption. In addition, the HT560 has power limiting function, one of which is amplitude limiting function, which limits a certain output amplitude at the output end to prevent damage to the horn. Another type is the AGC anti distortion function, which, when turned on, can effectively improve the distortion caused by excessive input amplitude or reduced power supply voltage.

In addition, the HT560 has a built-in shutdown function to minimize standby current, and also integrates functions such as output overcurrent protection, on-chip overheating protection, and power supply undervoltage abnormal protection.
