TPA3221 is a high-power class D amplifier that can achieve high efficiency 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 4 ohm load or 1 x 208W power for a 2 ohm load.
The main filter electrolytic capacitor adopts the imported famous brand Erkang with a capacity of 2200UF/35V*4 to ensure strong and continuous power support.
High-precision chip resistors are selected for the resistors to ensure a good signal-to-noise ratio of the whole machine.
Adopt special magnetic ring inductor for audio to ensure the sound is clear and powerful.
Basic 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 ohm in BTL Configuration
112-W Stereo into 3 ohm in BTL Configuration
208-W Mono into 2 ohm in PBTL Configuration
Output Power at 1% THD N
88-W Stereo into 4 ohm in BTL Configuration
100-W Stereo into 3 ohm in BTL Configuration
170-W Mono into 2 ohm in PBTL Configuration
Closed-Loop Feedback Design
Signal Bandwidth up to 100 kHz for High-Frequency Content From HD Sources
0.02% THD N at 1 W into 4 ohm
60-dB PSRR (BTL, No Input Signal)
less than 75-μV Output Noise (A-Weighted)
more than 108-dB SNR (A-Weighted)
AD or HEAD Modulation Schemes
Low-Power Operating Modes
Standby Modes: Mute and less than 1 mA Shutdown
Low Idle-Current HEAD Modulation Scheme
Single-Channel BTL Operation
Multiple Input Options to Simplify Pre-Amp Design
Differential or Single-Ended Analog Inputs
Selectable Gains: 18 dB, 24 dB, 30 dB, 34 dB
Integrated Protection: Undervoltage, Overvoltage, Cycle-by-cycle Current Limit, Short Circuit, Clipping Detection, Overtemperature Warning andShutdown, and DC Speaker Protection
