Product details

Temperature grade and environment

Rated for -40°C to 85°C ambient, so it suits outdoor telecom enclosures, automotive cabin audio (non-underhood), and industrial panel speakers where the environment sees temperature swings. The industrial range also covers portable gear left in vehicles or exposed to direct sunlight.

Lifecycle and sourcing

Listed as Active with no end-of-life notice. The part is RoHS non-compliant, so verify your assembly line's exemption or plan for a lead-free alternative if your process requires RoHS. Sourced through independent distribution; availability and pricing are confirmed at quote time against an RFQ.

Frequently asked questions

What is the output power of MAX9719AEUE?

It delivers 1.4W per channel into a 4Ω load, stereo (2-channel).

Does MAX9719AEUE require an external heatsink?

No external heatsink is required if the exposed pad is soldered to a sufficient PCB copper area for thermal dissipation. Without that, thermal shutdown may activate under sustained 1.4W output.
