Product details

35W mono or 17.5W stereo — the output power decision

The MAX9736AETJ+T is a Class D audio amplifier from Maxim Integrated that delivers 35W into a 4Ω load in mono mode, or 17.5W per channel into 8Ω loads in stereo mode. This output power range targets powered speakers, soundbars, subwoofer plates, and commercial audio systems where efficiency matters — Class D keeps heat dissipation low enough for the 32-TQFN package with exposed pad.

Supply range and protection features

Operating from 8V to 28V, the amplifier works with common unregulated or regulated supply rails — 12V, 18V, or 24V bricks are all in range. On-chip short-circuit and thermal protection, plus depop and mute, simplify the system design: no external muting relay or separate protection supervisor needed.

Package and mounting for layout planning

Housed in a 32-WQFN with exposed pad (supplier package 32-TQFN 7x7 mm), the part is surface-mount only.

It is not automotive-qualified (no AEC-Q100 cited), so it fits home theater, pro audio racks, and public-address systems rather than under-hood or cabin audio.

Frequently asked questions

Is MAX9736AETJ+T mono or stereo?

It supports both: 1-channel (mono) at 35W into 4Ω, or 2-channel (stereo) at 17.5W per channel into 8Ω. The output mode is selected by the application circuit.

Does MAX9736AETJ+T have thermal protection?

Yes, it includes on-chip short-circuit and thermal protection, plus depop, mute, and shutdown features.
