This output level suits line-level speaker drivers, headphone amplifiers, or audio alert transducers in portable and fixed equipment where a single-supply rail between 2.7V and 5.5V is available — a 3.3V or 5V system rail, or a single-cell Li-ion battery, directly powers the output stage without a separate boost converter. The 2-channel (stereo) output covers left-right audio paths in a single IC, saving board area compared to a dual-mono implementation. ## 16-TQFN (4x4 mm) — thermal and footprint constraints Packaged in a 16-WQFN with exposed pad (supplier device package 16-TQFN, 4x4 mm), the MAX9719CETE requires a thermal land on the PCB to sink heat from the output stage. Confirm feeder compatibility before committing the line. ## Active lifecycle, RoHS constraint It remains a current-production part available through authorized distribution channels. A critical sourcing note: the device is RoHS non-compliant. This restricts its use in EU RoHS-regulated products and many consumer electronics BOMs. For RoHS-compliant designs, a lead-free variant (MAX9719CETE+) or a functionally equivalent Class D alternative should be evaluated. The non-compliant status also affects reflow profiles — the solder alloy and peak temperature must match the tin-lead finish, not the lead-free SAC profile.","metaTitle":"MAX9719CETE Analog Devices Class AB Stereo Amp","metaDescription":"MAX9719CETE Analog Devices Class AB stereo audio power amplifier, 1.4W x 2 @ 4Ω, 2.7-5.5V supply, industrial temp, active production.
