The MAX9703/MAX9704 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 15W while

offering up to 78% efficiency. Proprietary and patent-pro-

tected modulation and switching schemes render the tra-

ditional Class D output filter unnecessary.

The MAX9703/MAX9704 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.

The MAX9703/MAX9704 feature high 80dB PSRR, low

0.07% THD+N, and SNR in excess of 95dB. Short-cir-

cuit and thermal-overload protection prevent the

devices from being damaged during a fault condition.

The MAX9703 is available in a 32-pin TQFN (5mm x

5mm x 0.8mm) package. The MAX9704 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.
