MAX9765, MAX9766, MAX9767 750mW Audio Amplifiers With Headphone Amp, Microphone Preamp, And Input Mux

The MAX9765 MAX9766 MAX9767 family combines speaker, Headphone and Microphone Amplifiers all in a small thin QFN package. The MAX9765 is targeted at stereo speaker playback applications and includes a stereo bridge-tied load (BTL) speaker amp, stereo Headphone amp, single-ended output mic amp, input MUX, and IC control. The MAX9766 is targeted at mono speaker playback applications and includes a mono BTL speaker amp, stereo Headphone amp, differential output mic amp, input MUX, and IC control. The MAX9767 is targeted at applications that do not require a Headphone amp and includes a stereo BTL speaker amp, differential output mic amp, and parallel control.
These devices operate from a single 2.7V to 5.5V supply. A high 95dB PSRR allows these devices to operate from noisy supplies without additional power conditioning. An ultra-low 0.003% THD+N ensures clean, low distortion amplification of the Audio signal. Patented click-and-pop suppression eliminates audible transients on power and shutdown cycles.
In speaker mode, the Amplifiers CAN deliver up to 750mW of continuous average power into a 4 load. In Headphone mode, the Amplifier CAN deliver up to 65mW 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 MAX9765 MAX9766 also feature a 2:1 input multiplexer, allowing multiple Audio sources to be selected. The various functions are controlled by either an IC-compatible MAX9765 MAX9766 or simple parallel control Interface MAX9767 .
All devices include two low-noise Microphone preamps, a differential amp for internal Microphones and a single-ended Amplifier for additional external Microphones A Microphone bias output is provided, reducing external component count.
The MAX9765 MAX9766 MAX9767 are available in a thermally efficient 32-pin thin QFN package (5mm x 5mm x 0.8mm). All devices have short-circuit and thermal-overload protection (OVP) and are specified over the extended -40C to +85C temperature range.
