TPA3221 digital power amplifier board module 2.1 sound channel D class HIFI audio amplifier 100W*2 YJ

 TPA3221 digital power amplifier board module 2.1 sound channel D class HIFI audio amplifier 100W*2

The TPA3221 is a high-power Class D amplifier that can operate efficiently at full power, idle and standby. The device uses closed-loop feedback with bandwidth up to 100kHz to provide low distortion in the audio frequency band and achieve excellent quality. The device in the AD or low idle current HEAD (efficient AD mode) modulation, and can provide 2 x 4 Ω load power of 105 w, or for 2 Ω provide 1 x 208 w power load.
