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 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 eliminates audible transients on power and shutdown cycles. Power-saving features include low 4mV V_OS (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 continuous average power into a 16Ω 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 I²C-compatible or simple parallel control interface.

The MAX9760–MAX9763 are available in either a thermally efficient 28-pin thin QFN package (5mm x 5mm x 0.8mm) or a TSSOP-EP package. All devices have thermal overload protection (OVP) and are specified over the extended -40°C to +85°C temperature range.
