2.6W Stereo Audio Power Amplifiers and

DirectDrive Headphone Amplifiers

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 patented DirectDrive

architecture 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

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.

♦ 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

The MAX9750/MAX9751/MAX9755 are offered in space-

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

x 0.8mm) and 28-pin TSSOP-EP packages. Both devices

have thermal-overload and output short-circuit protec-

tion, and are specified over the extended -40°C to +85°C

temperature range.

♦ Analog Volume Control (MAX9750)

♦ Beep Input with Glitch Filter (MAX9750)

♦ 2:1 Stereo Input MUX (MAX9751)

♦ ±±kV ꢀSD-Protected Headphone Driver Outputs
