3.2W, High-Efficiency, Low-EMI, Filterless,

Class D Audio Amplifier

General Description

Features

The MAX9759 mono class D, audio power amplifier

provides class AB amplifier audio performance with the

benefits of class D efficiency, eliminating the need for a

heatsink and extending battery life. The MAX9759 deliv-

ers up to 3.2W of continuous power into a 4 load while

offering greater than 90% efficiency. Maxim’s next-gen-

eration, low-EMI modulation scheme allows the amplifi-

er to operate without an external LC filter while still

meeting FCC EMI-radiated emission levels.

♦ 3.2W into 4 Load (THD+N = 10%)

♦ Filterless Amplifier Passes FCC Radiated

Emissions Standards with 7.6cm of Cable

♦ 92% Efficiency

♦ High PSRR (81dB at 1kHz)

♦ Low 0.02% THD+N

♦ External Clock Synchronization for Multiple,

The MAX9759 offers two modulation schemes: a fixed-

frequency modulation (FFM) mode and a spread-spec-

trum modulation (SSM) mode. The SSM mode flattens

the wideband spectral components, reducing EMI-radi-

ated emissions due to the modulation frequency.

Furthermore, the MAX9759 oscillator can be synchro-

nized to an external clock through the SYNC input,

allowing the switching frequency to range from

1000kHz to 1600kHz. The SYNC input and SYNC_OUT

output of the MAX9759 allow multiple Maxim class D

amplifiers to be cascaded and frequency locked, mini-

mizing interference due to clock intermodulation. The

MAX9759 utilizes fully differential input amplifiers, a full-

bridged output, comprehensive click-and-pop suppres-

sion, and features four selectable gain settings (6dB,

12dB, 18dB, 24dB).

Cascaded Maxim Class D Amplifiers

♦ 3.0V to 5.5V Single-Supply Operation

♦ Pin-Selectable Gain (6dB, 12dB, 18dB, 24dB)

♦ Integrated Click-and-Pop Suppression

♦ Low Quiescent Current (8.4mA)

♦ Low-Power Shutdown Mode (10µA)

♦ Mute Function

♦ Short-Circuit and Thermal-Overload Protection

♦ Available in Thermally Efficient Packages

16-Pin TQFN (4mm x 4mm x 0.8mm)

16-Pin TSSOP

The MAX9759 features high 81dB PSRR, low 0.02%

THD+N, and SNR in excess of 90dB. Short-circuit and

thermal-overload protection prevents damage to the

device during a fault condition. The MAX9759 operates

from a single 5V supply, consumes 8.4mA of supply

current, and is available in a 16-pin thin QFN package

(4mm x 4mm x 0.8mm) and a 16-pin TSSOP package.

The MAX9759 is fully specified over the extended -40°C

to +85°C temperature range.
