This datasheet also covers the MAX9777 variant, as both devices belong to the same stereo 3w audio power amplifiers family and are provided as variant models within a single manufacturer datasheet.
General Description
The MAX9777/MAX9778 combine a stereo 3W bridgetied load (BTL) audio power amplifier, stereo singleended (SE) headphone amplifier, headphone sensing, and a 2:1 input multiplexer all in a tiny 28-pin thin QFN package.
Key Features
include low 4mV VOS (minimizes DC current drain through the speakers), low 13mA supply current, and a 10µA shutdown 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 headphone mode, the amplifier can deliver up to 200mW of cont.
Note: The manufacturer provides a single datasheet file (MAX9777_MaximIntegratedProducts.pdf) that lists specifications for multiple related part numbers.

nput Mux General Description The MAX9777/MAX9778 combine a stereo 3W bridgetied load (BTL) audio power amplifier, stereo singleended (SE) headphone amplifier, headphone sensing, and a 2:1 input multiplexer all in a tiny 28-pin thin QFN package. These devices operate from a single 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-distortion amplification of the audio signal. Patented click-andpop suppression minimizes audible transients on power and shutdown cycles.
