That power stage runs off a 4.5V to 26.4V supply, while the digital control logic uses a separate 1.62V to 3.63V rail — two independent regulators on the board, not one. ## Industrial temperature range limits the deployment envelope The exposed-pad HTSSOP package is MSL 3 out of the bag; if the moisture-barrier bag has been open past the floor-life window, a bake before reflow is required. ## Dual supply rails — two regulators, not one The 1.62V–3.63V digital supply powers the I²C control interface and internal logic; the 4.5V–26.4V power-stage supply feeds the output bridge. A common mistake is trying to run both from a single rail — the power-stage voltage sets the output swing, and dropping it below 4.5V shuts down the amplifier. The digital rail can be 1.8V or 3.3V depending on the host controller's logic level. Both rails must be present and within range before the device exits shutdown.","metaTitle":"TAS5806MDCPR Class-D Audio Amp, 45W Mono / 23W Stereo","metaDescription":"Texas Instruments TAS5806MDCPR Class-D audio amplifier IC. 45W x 1 @ 4Ω or 23W x 2 @ 8Ω. 38-HTSSOP.

For a functionally similar Class-D amp with a different footprint, the TAS5825M series offers comparable power levels."},{"question":"Is TAS5806MDCPR compatible with 8 ohm speakers?","answer":"Yes. The TAS5806MDCPR is rated for 23W per channel into 8Ω loads in stereo mode. It also supports 4Ω loads in mono mode at 45W. The output configuration is selectable via the I²C control interface."},{"question":"Does TAS5806MDCPR have a boost converter?","answer":"No. The TAS5806MDCPR does not include an integrated boost converter. It requires an external power-stage supply rail between 4.5V and 26.4V. For battery-powered designs needing a regulated higher-voltage rail from a lower input, an external boost converter is required upstream."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TAS5806MDCPR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TAS5806MDCPR when reusing this data.
