915 Generation TPA3221 Digital Power Amplifier Board Digital Class D HIFI

Detailed Information About The Product:

TPA3221 is a high-power Class D amplifier that can achieve high-efficiency operation in full power, idle and standby states.
The device uses closed-loop feedback with a bandwidth of up to 100kHz to provide low distortion in the audio frequency band and achieve excellent quality.
The device operates with AD or low idle current HEAD (high-efficiency AD mode) modulation and can provide 2 x 105W power for a 4Ω load or 1 x 208W power for a 2Ω load.
Integrated Protection: Undervoltage, Overvoltage, Cycle-by-cycle Current Limit, Short Circuit, Clipping Detection, Overtemperature Warning andShutdown, and DC Speaker Protection
