MAX9768

10W Mono Class D Speaker

Amplifier with Volume Control

General Description

The MAX9768 mono 10W Class D speaker amplifier pro-

vides high-quality, efficient audio power with an integrated

volume control function.

Features

● 10W Output (8Ω, PV

= 14V, THD+N = 10%)

● Spread-Spectrum Modulation

● Meets EN55022B EMC with Ferrite Bead Filters

● Amplifier Operation from 4.5V to 14V Supply

The MAX9768 features a 64-step dual-mode (analog or

digitally programmable) volume control and mute function.

The audio amplifier operates from a 4.5V to 14V single

supply and can deliver up to 10W into an 8Ω speaker with

a 14V supply.

● 64-Step Integrated Volume Control (I C or Analog)

● Low 0.08% THD+N (R = 8Ω, P

= 6W)

OUT

● High 77dB PSRR

A selectable spread-spectrum mode reduces EMI-

radiated emissions, allowing the device to pass EMC

testing with ferrite bead filters and cable lengths up to 1m.

The MAX9768 can be synchronized to an external clock,

allowing synchronization of multiple Class D amplifiers.

● Two t

Times Offered

• MAX9768—220ms

• MAX9768B—15ms

● Low-Power Shutdown Mode (0.5μA)

● Short-Circuit and Thermal-Overload Protection

The MAX9768 features high 77dB PSRR, low 0.08%

THD+N, and SNR up to 97dB. Robust short-circuit and

thermal-overload protection prevent device damage during

a fault condition. The MAX9768 is available in a 24-pin thin

QFN-EP (4mm x 4mm x 0.8mm) package and is specified

over the extended -40°C to +85°C temperature range.

Pin Configuration located toward end of data sheet.

Ordering Information located at end of data sheet.

Applications

● Notebook Computers

● Flat-Panel Displays

● Multimedia Monitors

● GPS Navigation Systems

● Security/Personal Mobile Radio
