Product details

Class D stereo amplifier — 20W per channel into 8Ω

The MAX98400AETX+T from Maxim Integrated is a 2-channel (stereo) Class D audio amplifier delivering 20W per channel into an 8Ω load. Class D topology keeps efficiency above 85% at full output, so the 36-TQFN exposed-pad package can dissipate the heat without a large heatsink in many designs. Supply range is 8V to 28V, giving flexibility for single-rail or regulated supplies in powered speakers, soundbars, or industrial audio systems.

Housed in a 36-TQFN exposed pad (6x6 mm body).

Frequently asked questions

Can MAX98400AETX+T drive a 4-ohm speaker?

Yes, the amplifier can drive a 4Ω load, but the output power will be higher than the 20W x 2 @ 8Ω rating. The actual power depends on the supply voltage and thermal limits; ensure adequate heatsinking and stay within the -40°C to 85°C operating range.

Is MAX98400AETX+T lead-free and RoHS compliant?

Yes, the MAX98400AETX+T is ROHS3 compliant, meaning it meets the Restriction of Hazardous Substances directive with no exemptions for lead.
