General Description
The MAX9760–MAX9763 family combines a stereo or
mono 3W bridge-tied load (BTL) audio power amplifier,
stereo single-ended headphone amplifier, headphone
sensing, and a 2:1 input multiplexer all in a tiny 28-pin
thin QFN package. These devices operate from a sin-
gle 4.5V to 5.5V supply and feature an industry-leading
100dB PSRR, allowing these devices to operate from
noisy supplies without the addition of a linear regulator.
An ultra-low 0.002% THD+N ensures clean, low-distor-
tion amplification of the audio signal. Click-and-pop
suppression eliminates audible transients on power and
shutdown cycles. Power-saving features include low
4mV VOS (minimizes DC current drain through the
speakers), low 13mA supply current, and a 10A shut-
down mode. A MUTE function allows the outputs to be
quickly enabled or disabled.
A headphone sense input detects the presence of a
headphone jack and automatically configures the
amplifiers for either speaker or headphone mode. In
speaker mode, the amplifiers can deliver up to 3W of
continuous average power into a 3Ω load. In head-
phone mode, the amplifier can deliver up to 200mW of
continuous average power into a 16Ω load. The gain of
the amplifiers is externally set, allowing maximum flexi-
bility in optimizing output levels for a given load. The
amplifiers also feature a 2:1 input multiplexer, allowing
multiple audio sources to be selected. The multiplexer
can also be used to compensate for limitations in the
frequency response of the loud speakers by selecting
an external equalizer network. The various functions are
controlled by either an I2C-compatible or simple parallel
control interface.
The MAX9760–MAX9763 are available in either a ther-
mally efficient 28-pin thin QFN package (5mm 5mm
0.8mm) or a TSSOP-EP package. All devices have ther-
mal overload protection (OVP) and are specified over
the extended -40°C to +85°C temperature range.
