TPA3221 Digital Amplifier Board Digital Class D HIFI

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