Product details

1.4 W per channel into 4 Ω — the headline number that defines the load

The MAX9719DETE: The Class AB output stage keeps crossover distortion low at the expense of quiescent current, which means the supply headroom matters: at 5.5 V the amp hits its rated power; at 2.7 V the available swing is reduced and the maximum output drops accordingly.

Package and board-fit — 16-TQFN with exposed pad

Housed in a 16-WQFN exposed pad package (4x4 mm body, supplier device package 16-TQFN), the MAX9719DETE requires a thermal land on the PCB to pull heat from the die.

Active lifecycle — but RoHS non-compliant

Because the part is active, it is sourced through authorized distribution channels.

Frequently asked questions

Is MAX9719DETE RoHS compliant?

No — the RoHS status is non-compliant. This means the part contains lead or other restricted substances above the exemption thresholds. For RoHS-required BOMs, a lead-free alternative or a waiver must be evaluated.

What is the maximum output power of MAX9719DETE?

The actual output depends on supply voltage, load impedance, and thermal conditions.
