Product details

The MAX9719BETE is supplied in a 16-WQFN exposed pad package (4x4 mm TQFN footprint).

Output power and load matching

Each channel delivers 1.4 W into a 4 Ω load — enough for small desktop speakers, portable Bluetooth speakers, or headphone amplifiers where the thermal budget of the 4x4 mm package is the limiting factor, not the silicon itself. The Class AB output stage means quiescent current is higher than a Class D equivalent, but the linearity avoids the switching noise and output filter that a Class D design requires. For battery-powered gear, the trade-off is standby time vs. audio fidelity.

Lifecycle and compliance

RoHS compliance is not claimed for this variant. If your BOM requires RoHS exemption documentation or a lead-free finish, confirm the date-code and plating before committing the line.

Frequently asked questions

What is the closest pin-compatible alternative to MAX9719BETE in this Analog & Data Acquisition family?

The MAX9719BETE is a stereo Class AB amplifier in a 16-TQFN (4x4) package; a functional replacement would require evaluating other Analog Devices stereo audio amps with similar supply and output ratings, but pin compatibility is not guaranteed without a board layout change.
