TPA3221 Stereo BTL 100W*2 Digital Power Amplifier Board Home Audio Amlifier AD Mode Operation DC24V 1PC

TPA3221 100W*2 Digital power amplifier board cla D home audio Amplifier . Product Descrtion: TPA3221 is a high-power cla D amplifier that can achieve high-efficiency operation in full power, idle and standby states. The device uses closed-loop feedba 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. Product performance parameters: Wide 7-V to 30-V Supply Voltage Operation . • Stereo (2 x BTL) and Mono (1 x PBTL) Operation . • Output Power at 10% THD+N . – 105-W Stereo into 4 Ω in BTL Configuration . – 112-W Stereo into 3 Ω in BTL Configuration . – 208-W Mono into 2 Ω in PBTL Configuration . • Output Power at 1% THD+N . – 88-W Stereo into 4 Ω in BTL Configuration . – 100-W Stereo into 3 Ω in BTL Configuration . – 170-W Mono into 2 Ω in PBTL Configuration . • 5-V Gate Drive or Built-in LDO for Optional Single-Supply Operation . • Closed-Loop Feedba Design . – Signal Bandwidth up to 100 kHz for High-Frequency Content From HD Sources . – 0.02% THD+N at 1 W into 4 Ω . – 60-dB PSRR (BTL, No Input Signal) . – 108-dB SNR (A-Weighted) . – AD or HEAD Modulation Schemes . • Low-Power Operating Modes . – Standby Modes: Mute and < 1 mA Shutdown . – Low Idle-Current HEAD Modulation Scheme . – Single-Channel BTL Operation . • Multle Input Options to Simplify Pre-Amp Design . – Differential or Single-Ended og Inputs . – Selectable Gains: 18 dB, 24 dB, 30 dB, 34 dB. • Integrated Protection: Undervoltage, Overvoltage,Cycle-by-cycle Current Limit, Short Circuit,Clping Detection, Overtemperature Warning andShutdown, and DC Speaker Protection . • 90% Efficient Cla-D Operation (4 Ω) . • Pin-Compatible Family of Devices with Voltageand Power-Level Options .
