It delivers 2.6W per channel into a 3 Ω load, runs from a single 4.5 V to 5.5 V supply, and operates over the -40°C to 85°C industrial temperature range. The 28-TSSOP package integrates a stereo speaker channel plus a separate stereo headphone output, making it a single-IC audio solution for multimedia docks, portable speakers, automotive infotainment head units, and industrial panel audio. ## Output power and load matching The headline rating is 2.6W per channel into 3 Ω. That figure sets the minimum speaker impedance for full output. ## Temperature grade and environment Rated for -40°C to 85°C ambient, this part suits outdoor telecom enclosures, automotive cabin audio, and factory-floor sound systems where the enclosure sees temperature swings. The 28-TSSOP package is surface-mount, so reflow soldering is standard; the industrial temperature rating means the silicon is specced for the full range without derating output power at the hot end. ## Lifecycle and sourcing The MAX9750BEUI carries an Active lifecycle status — no end-of-life notice, no last-time-buy window. It is sourced through independent distribution and quoted to order against an RFQ.","metaTitle":"MAX9750BEUI Class AB Audio Amp, 2.6W x 2 @ 3Ω, 28-TSSOP","metaDescription":"MAX9750BEUI Class AB stereo audio power amplifier with DirectDrive®. 2.6W per channel into 3Ω, 4.5V–5.5V supply, -40°C to 85°C.
