6W, Filterless, Spread-Spectrum

Mono/Stereo Class D Amplifiers

General Description

Features

♦ Filterless Class D Amplifier

The MAX9713/MAX9714 mono/stereo class D audio

power amplifiers provide class AB amplifier performance

with class D efficiency, conserving board space and

eliminating the need for a bulky heatsink. Using a class

D architecture, these devices deliver up to 6W while

offering greater than 85% efficiency. Proprietary and

patent-protected modulation and switching schemes

render the traditional class D output filter unnecessary.

♦ Unique Spread-Spectrum Mode Offers 5dB

Emissions Improvement Over Conventional

Methods

♦ Up to 85% Efficient

♦ 6W Output Power into 8Ω

♦ Low 0.07% THD+N

♦ High PSRR (76dB at 1kHz)

The MAX9713/MAX9714 offer two modulation schemes:

a fixed-frequency mode (FFM), and a spread-spectrum

mode (SSM) that reduces EMI-radiated emissions due

to the modulation frequency. The device utilizes a fully

differential architecture, a full bridged output, and com-

prehensive click-and-pop suppression.

♦ 10V to 25V Single-Supply Operation

♦ Differential Inputs Minimize Common-Mode Noise

♦ Pin-Selectable Gain Reduces Component Count

♦ Industry-Leading Integrated Click-and-Pop

Suppression

The MAX9713/MAX9714 feature high 76dB PSRR, low

0.07% THD+N, and SNR in excess of 100dB. Short-cir-

cuit and thermal-overload protection prevent the

devices from being damaged during a fault condition.

The MAX9713 is available in a 32-pin TQFN (5mm x

5mm x 0.8mm) package. The MAX9714 is available in a

32-pin TQFN (7mm x 7mm x 0.8mm) package. Both

devices are specified over the extended -40°C to

+85°C temperature range.

♦ Low Quiescent Current (18mA)

♦ Low-Power Shutdown Mode (0.2µA)

♦ Short-Circuit and Thermal-Overload Protection

♦ Available in Thermally Efficient, Space-Saving
