The MAX9716/MAX9717 audio power amplifiers are ideal

for portable audio devices with internal speakers. A

bridge-tied load (BTL) architecture minimizes external

component count, while providing high-quality audio

reproduction. Both devices deliver 1.4W continuous

power into a 4Ω load with less than 1% Total Harmonic

Distortion (THD) while operating from a single +5V sup-

ply. With an 8Ω load, both devices deliver 1W continuous

power. These devices also deliver 350mW continuous

power into an 8Ω load while operating from a single

+3.0V supply. The devices are available as adjustable

gain amplifiers (MAX9716/MAX9717A) or with internally

fixed gains of 6dB, 9dB, and 12dB (MAX9717B/

MAX9717C/MAX9717D), reducing component count.

A low-power shutdown mode disables the bias generator

and amplifiers, reducing quiescent current consumption

to less than 10nA. These devices feature Maxim’s

industry-leading, comprehensive click-and-pop sup-

pression that reduces audible clicks and pops during

startup and shutdown.

The MAX9717 features a headphone sense input (BTL/SE)

that senses when a headphone is connected to the

device, disables the BTL slave driver, muting the speaker

while driving the headphone as a single-ended load.

The MAX9716 is pin compatible with the LM4890 and is

available in 9-bump UCSP™, 8-pin TDFN (3mm x

3mm), and 8-pin µMAX packages. The MAX9717 is

available in 9-bump UCSP, 8-pin TDFN, and 8-pin

µMAX packages. Both devices operate over the -40°C

to +85°C extended temperature range.
