2.6W Stereo Audio Power Amplifiers and

DirectDrive Headphone Amplifiers

01/MAX975

General Description

Features

The MAX9750/MAX9751/MAX9755 combine a stereo,

2.6W audio power amplifier and stereo DirectDrive^®

110mW headphone amplifier in a single device. The

headphone amplifier uses Maxim’s DirectDrive architec-

ture that produces a ground-referenced output from a

single supply, eliminating the need for large DC-blocking

capacitors, saving cost, space, and component height.

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

clean, low-distortion amplification of the audio signal.

♦ No DC-Blocking Capacitors Required—Provides

Industry’s Most Compact Notebook Audio

Solution

♦ PC2001 Compliant

♦ 5V Single-Supply Operation

♦ Class AB 2.6W Stereo BTL Speaker Amplifiers

♦ 110mW DirectDrive Headphone Amplifiers

♦ High 90dB PSRR

♦ Low-Power Shutdown Mode

♦ Industry-Leading Click-and-Pop Suppression

♦ Low 0.01% THD+N at 1kHz

♦ Short-Circuit and Thermal Protection

♦ Selectable Gain Settings

♦ Analog Volume Control (MAX9750)

♦ BEEP Input with Glitch Filter (MAX9750)

♦ 2:1 Stereo Input MUX (MAX9751)

The MAX9750 features an analog volume control, and a

BEEP input. The MAX9751 features a 2:1 input multiplexer,

allowing multiple audio sources to be selected. All devices

feature a single-supply voltage, a shutdown mode, logic-

selectable gain, and a headphone sense input. Industry-

leading click-and-pop suppression eliminates audible

transients during power and shutdown cycles.

The MAX9750/MAX9751/MAX9755 are offered in a

space-saving, thermally efficient 28-pin thin QFN (5mm

x 5mm x 0.8mm) package. These devices have thermal-

overload and output short-circuit protection, and are

specified over the extended -40°C to +85°C tempera-

ture range.
