The TPA3220DDWR from Texas Instruments is an analog input, Class-D audio amplifier designed for high-fidelity sound reproduction. It supports both stereo (2 x BTL) and mono (1 x PBTL) configurations, delivering up to 60-W stereo continuous power into 8 Ω or 110-W stereo peak power into 4 Ω at 10% THD+N. For higher quality, it provides 50-W stereo continuous into 8 Ω or 89-W stereo peak into 4 Ω at 1% THD+N.
This amplifier operates with a power stage supply voltage ranging from 7 V to 30 V and an analog supply voltage from 5 V to 30 V. It features a signal bandwidth up to 100 kHz, ensuring reproduction of high-frequency content from HD sources. The device boasts low idle current, low output noise (<72 µV A-weighted), and a high SNR (>108 dB A-weighted).
Integrated protection features include undervoltage, cycle-by-cycle current limit, short circuit, clipping detection, overtemperature warning and shutdown, and DC speaker protection. The TPA3220DDWR is housed in a thermally enhanced HTSSOP package, suitable for surface mounting. Its selectable gains of 18 dB, 24 dB, 30 dB, and 34 dB offer design flexibility.
With 90% efficiency at 4 Ω, this Class-D amplifier is suitable for various audio applications requiring robust power delivery and excellent audio quality, such as home audio systems, soundbars, and PC notebooks.
