The Texas Instruments TAS5805MPWPR is a high-performance Class-D audio amplifier designed for various audio applications. It supports multiple output configurations, delivering 2 x 23 W in stereo mode (8-Ω, 21 V, THD+N=1%) or 45 W in mono mode (4-Ω, 21 V, THD+N=1%).
This amplifier boasts excellent audio performance with THD+N ≤ 0.03% at 1 W, 1 kHz, and an SNR ≥ 107 dB (A-weighted). It features a digital input, Class-D architecture, and I2C control interface. The power stage supply voltage ranges from 4.5 V to 26.4 V, with an analog supply voltage range of 4.5 V to 26.4 V.
The TAS5805MPWPR operates within an ambient temperature range of -25°C to 85°C. It is housed in an HTSSOP (PWP) package with a body size of 62.08 mm² (9.7 mm × 6.4 mm). The device offers flexible power supply configurations and audio I/O options, including I2S, LJ, RJ, TDM, and a 3-Wire Digital Audio Interface without requiring MCLK.
Enhanced audio processing capabilities include multi-band DRC and AGL, thermal foldback, DC blocking, an input mixer, and an output crossbar. Integrated self-protection features safeguard against adjacent pin-to-pin shorts, over-current, over-temperature, and under/over-voltage conditions. Its inductor-less operation for most cases where PVDD ≤ 14V reduces solution size and component count.
