3-Channel, 2.3W, Filterless Class D Amplifiers  
with Active Crossover  
General Description  
Features  
The MAX9706/MAX9707 combine three high-efficiency  
Class D amplifiers with an active crossover to provide  
stereo highpass outputs, and a mono lowpass output.  
All three channels deliver up to 2.3W at 1% THD+N per  
channel into 4Ω when operating from a 5V supply.  
An internal active filter processes the stereo inputs (left  
and right) into stereo highpass and mono lowpass out-  
puts. The crossover frequency is pin-selectable to four  
different frequencies to accommodate a variety of  
speaker configurations. The internal Class D amplifiers  
feature low-EMI, spread-spectrum outputs. No output  
filters are required.  
♦ Triple Class D Amplifiers Deliver 3 x 2.3W into 4Ω  
♦ Internal Active Crossover Filter with Adjustable  
Crossover Frequency  
♦ Low-EMI, Spread-Spectrum Modulation  
♦ Low 0.02% THD+N  
♦ High PSRR (71dB)  
♦ DirectDrive Headphone Amplifier (MAX9706)  
♦ Enhanced Click-and-Pop Suppression  
♦ Input and Output Modulator Synchronization  
♦ Low-Power Shutdown Mode  
The MAX9706 features Maxim’s patented DirectDrive™  
headphone amplifier, providing ground-referenced  
headphone outputs without the need for bulky DC-cou-  
pling capacitors. The headphone outputs are capable  
of delivering 95mW per channel into 16Ω from a 3.3V  
supply, and are protected against ESD up to ±±kV.  
♦ Up To 90% Efficiency  
♦ Space-Saving (6mm x 6mm x 0.8mm) 36-Pin Thin  
QFN Package  
The MAX9706/MAX9707 feature pin-programmable  
gain, synchronization inputs and outputs, and a shut-  
down mode that reduces supply current to less than  
1µA. All amplifiers feature click-and-pop suppression  
circuitry. Both devices are fully specified over the -40°C  
to +±5°C extended temperature range and are avail-  
able in the thermally enhanced 36-pin (6mm x 6mm x  
0.±mm) thin QFN package.
