Product details

Class D amplifier for mono or stereo audio — 35W into 4Ω

Built-in depop, mute, short-circuit protection, and thermal shutdown reduce the external component count and improve system reliability. The output can be configured as a single mono channel or a stereo pair, letting one BOM line serve multiple product variants.

Active production — no end-of-life risk on this BOM line

If you need a reel variant, the MAX9736AETJ+T is the tape-and-reel version of the same die; the +T suffix is the only difference.

32-TQFN exposed pad — thermal and layout notes

The datasheet layout recommendation calls for a solid copper pour on the top layer, stitched with vias to the inner ground plane. Keep the output filter inductor and bypass capacitors close to the package to minimize radiated EMI from the switching output stage.

Frequently asked questions

What is the difference between MAX9736AETJ+ and MAX9736AETJ+T?

The only difference is the shipping medium: MAX9736AETJ+ comes in a tube, while MAX9736AETJ+T is the tape-and-reel version. The silicon, package, and electrical ratings are identical.

What is the maximum output power of MAX9736AETJ+?

35W into a 4Ω load with a single channel, or 17.5W per channel into 8Ω in stereo mode.

Does MAX9736AETJ+ require an external heatsink?

It depends on the output power and ambient temperature. The exposed pad on the 32-TQFN package is designed to be soldered to a PCB copper plane; for continuous 35W output at high ambient temperatures, additional heatsinking or forced airflow may be needed to stay within the thermal limits.
