For an 8Ω speaker, expect roughly half the power (~11W) at the same supply rail, since power scales inversely with load impedance for a given voltage swing. The 4.5V to 14V supply range means this amplifier runs from a single Li-ion cell (3.7V nominal boosted to 5V) up to a 12V automotive rail. At 14V the output swing is maximised; at lower rails the available power drops proportionally with the square of the supply voltage. ## Industrial temperature grade and thermal package The Class D architecture keeps efficiency above 85% typical, so the thermal load on the package is lower than a linear amplifier delivering the same output. Housed in a 44-WFQFN with exposed pad (supplier device package 44-TQFN 7x7 mm). ## Integrated features shrink the external BOM On-chip depop circuitry suppresses power-up and power-down clicks without external mute transistors. Short-circuit and thermal protection eliminate the need for a separate protection IC or PTC fuse on each channel. Volume control and shutdown are integrated — a DC voltage or I²C interface sets the gain, and the shutdown pin drops quiescent current to microamp levels. The mute function holds the outputs at mid-rail during start-up sequencing. ## RoHS compliance and documentation Listed as ROHS3 Compliant — no restricted substances above the threshold limits. The manufacturer provides full RoHS and REACH declarations with the shipment; no additional compliance documentation is required for EU or UKCA markets.","metaTitle":"MAX9744ETH+T Class D Stereo Amp, 22.5W x 2 @ 4Ω","metaDescription":"Active-production MAX9744ETH+T Class D stereo amplifier, 22.5W x 2 @ 4Ω, 4.5-14V supply, industrial temp range.
