General Description
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.
The MAX9706 features Maxim’s DirectDrive headphone
amplifier, providing ground-referenced headphone out-
puts without the need for bulky DC-coupling 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 ±8kV.
The MAX9706/MAX9707 feature pin-programmable
gain, synchronization inputs and outputs, and a shut-
down mode that reduces supply current to less than
1A. All amplifiers feature click-and-pop suppression
circuitry. Both devices are fully specified over the -40°C
to +85°C extended temperature range and are avail-
able in the thermally enhanced 36-pin (6mm x 6mm x
0.8mm) thin QFN package.
