General Description
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 4
load with less than 1% Total Harmonic
Distortion (THD) while operating from a single +5V sup-
ply. With an 8
load, both devices deliver 1W continuous
power. These devices also deliver 350mW continuous
power into an 8
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 MAX packages. The MAX9717 is
available in 9-bump UCSP, 8-pin TDFN, and 8-pin
MAX packages. Both devices operate over the -40°C
to +85°C extended temperature range.
