MAX9736

Mono/Stereo High-Power Class D Amplifier

General Description

Features

● Independently Controlled Dual Paths

● Wide 8V to 28V Supply Voltage Range

The MAX9736A/B/D Class D amplifiers provide high-

performance, thermally efficient amplifier solutions. The

MAX9736A delivers 2 x 15W into 8Ω loads, or 1 x 30W

into a 4Ω load. The MAX9736B/D deliver 2 x 6W into 8Ω

loads or 1 x 12W into a 4Ω load.

● Spread-Spectrum Modulation Enables Low EMI

Solution

● Passes CE EMI Limits with Low-Cost Ferrite

Bead/Capacitor Filter

● Low BOM Cost

● High 67dB PSRR at 1kHz Reduces Supply Cost

● 88% Efficiency Eliminates Heatsink

● Thermal and Output Current Protection

● < 1μA Shutdown Mode

These devices operate from 8V to 28V and provide a high

PSRR, eliminating the need for a regulated power supply.

The MAX9736 offers up to 88% efficiency at 12V supply.

Pin-selectable modulation schemes select between filter-

less modulation and classic PWM modulation. Filterless

modulation allows the MAX9736 to pass CE EMI limits

with 1m cables using only a low-cost ferrite bead and

capacitor on each output. Classic PWM modulation is

optimized for best audio performance when using a full

LC filter.

● Mute Function

● Space-Saving, 32-Pin TQFN Packages, 7mm x 7mm

x 0.8mm (MAX9736A/B), 5mm x 5mm x 0.8mm

(MAX9736D)

A pin-selectable stereo/mono mode allows stereo opera-

tion into 8Ω loads or mono operation into 4Ω loads. In

mono mode, the right input op amp becomes available as

a spare device, allowing flexibility in system design.

Applications

● LCD/PDP/CRT Monitors

● LCD/PDP/CRT TVs

● MP3 Docking Stations

● Notebook PCs

Comprehensive click-and-pop reduction circuitry mini-

mizes noise coming into and out of shutdown or mute.

● PC Speakers

Input op amps allow the user to create summing amplifiers,

lowpass or highpass filters, and select an optimal gain.

● All-in-One PCs

The MAX9736A/B/D are available in 32-pin TQFN packages

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