MAX9777, MAX9778 Stereo 3W Audio Power Amplifiers With Headphone Drive And Input Mux

The MAX9777 MAX9778 combine a stereo 3W bridge-tied load (BTL) Audio Power Amplifier stereo single-ended (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-and-pop suppression minimizes 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 shutdown mode. A MUTE function allows the outputs to be quickly enabled or disabled.
A Headphone sense input detects th 501 e 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 3 load. In Headphone mode, the Amplifier CAN deliver up to 200mW of continuous average power into a 16 load. The gain of the Amplifiers is externally set, allowing maximum flexibility 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 IC*-compatible MAX9777 or simple parallel control Interface MAX9778 .
The MAX9777 MAX9778 are available in a thermally efficient 28-pin thin QFN package (5mm x 5mm x 0.8mm). These devices have thermal-overload protection (OVP) and are specified over the extended -40C to +85C temperature range.
