A single 4 Ω subwoofer or a pair of 8 Ω satellites both fit within the same device, selected by the I²C control interface. ## Supply rails and thermal envelope Operates from a 3 V to 3.6 V supply, which means a single 3.3 V rail powers the entire amplifier — no separate high-voltage bus needed. The 0°C to 85°C ambient range covers indoor consumer and commercial audio gear but not automotive or extended industrial environments. Housed in a 48-HTQFP (7x7 mm) package with an exposed PowerPAD — the thermal pad must be soldered to a copper plane on the PCB to keep the junction temperature within limits at full output. The 48-PowerTQFP footprint is the same; the datasheet's land pattern is the reference. ## Integrated protection and digital audio interface Short-circuit and thermal protection are built in — no external clamp or sense resistor required on the output stage. The digital inputs accept I²S audio data directly, and the I²C bus handles volume, mute, and depop control. The depop feature suppresses the turn-on thump that otherwise couples through the speaker. ## Lifecycle and compliance The part is suitable for new designs and is sourced through authorized and independent distribution; lead time and pricing are confirmed at RFQ.","metaTitle":"TAS5731MPHPR Class D Amp, 69.6W x 1 @ 4Ω, 48-HTQFP","metaDescription":"Active TAS5731MPHPR Class D audio amp, 69.6W mono or 37.2W stereo, 3-3.6V supply, 48-HTQFP.
