2.2W Stereo Audio Power Amplifier

with Analog Volume Control

General Description

Features

♦ Class AB, 2.2W, Stereo BTL Speaker Amplifiers

♦ Analog Volume Control

The MAX9787 combines a stereo, 2.2W audio power

amplifier with an analog volume control in a single device.

A high 90dB PSRR and low 0.01% THD+N ensures clean,

low-distortion amplification of the audio signal.

♦ BEEP Input with Glitch Filter

♦ 5V Single-Supply Operation

The analog volume control can be driven with a poten-

tiometer, an RC-filtered PWM source, or a DAC output.

A BEEP input allows the addition of alert signals from

the controller to the audio path.

♦ High 90dB PSRR

♦ Low-Power Shutdown Mode

♦ Industry-Leading Click-and-Pop Suppression

♦ Low 0.01% THD+N at 1kHz

Industry-leading, click-and-pop suppression eliminates

audible transients during power and shutdown cycles.

Other features include single-supply voltage, a shut-

down mode, logic-selectable gain, thermal-overload,

and output short-circuit protection.

♦ Short-Circuit and Thermal Protection

♦ Selectable-Gain Settings

♦ Space-Saving 28-Pin TQFN (5mm x 5mm x 0.8mm)

The MAX9787 is offered in a space-saving, thermally

efficient, 28-pin, thin QFN (5mm x 5mm x 0.8mm) pack-

age, and is specified over the extended -40°C to +85°C

temperature range.
