2 x 1.5W, Stereo Class D Audio Subsystem

with DirectDrive Headphone Amplifier

5/MAX976

General Description

Features

♦ Unique Spread-Spectrum Modulation and Active

The MAX9775/MAX9776 combine a high-efficiency

Class D, stereo/mono audio power amplifier with a

mono DirectDrive^®receiver amplifier and a stereo

DirectDrive headphone amplifier.

Emissions Limiting Significantly Reduces EMI

♦ 3D Stereo Enhancement (MAX9775 Only)

♦ Up to 3 Stereo Inputs

Maxim’s 3rd-generation, ultra-low-EMI, Class D audio

power amplifiers provide Class AB performance with

Class D efficiency. The MAX9775/MAX9776 deliver

1.5W per channel into a 4Ω load from a 5V supply and

offer efficiencies up to 79%. Active emissions limiting

circuitry and spread-spectrum modulation greatly

reduce EMI, eliminating the need for output filtering

found in traditional Class D devices.

♦ 1.5W Stereo Speaker Output (4Ω, V

= 5V)

♦ 50mW Mono Receiver/Stereo Headphone Outputs

(32Ω, V = 3.3V)

♦ High PSRR (68dB at 217Hz)

♦ 79% Efficiency (V

= 3.3V, R = 8Ω, P

OUT

470mW)

♦ I²C Control—Input Configuration, Volume Control,

Output Mode

The MAX9775/MAX9776 utilize a fully differential archi-

tecture, a full-bridged output, and comprehensive click-

and-pop suppression. A 3D stereo enhancement

function allows the MAX9775 to widen the stereo sound

field immersing the listener in a cleaner, richer sound

experience than typically found in portable applications.

The devices utilize a flexible, user-defined mixer archi-

tecture that includes an input mixer, volume control, and

output mixer. All control is done through I²C.

♦ Click-and-Pop Suppression

♦ Low Total Harmonic Distortion (0.03% at 1kHz)

♦ Current-Limit and Thermal Protection

♦ Available in Space-Saving, 36-Bump WLP (3mm x

3mm) and 32-Pin TQFN (5mm x 5mm) Packages

Ordering Information

CLASS D

AMPLIFIER

PART

PIN-PACKAGE

The mono receiver amplifier and stereo headphone

amplifier use Maxim’s DirectDrive architecture that pro-

duces a ground-referenced output from a single supply,

eliminating the need for large DC-blocking capacitors,

saving cost, space, and component height.
