General Description
The MAX9737 mono 7W Class D amplifier provides a
high-performance, thermally efficient amplifier solution
that offers up to 88% efficiency at a 12V supply. The
device operates from 8V to 28V and provides a high 80dB
PSRR, eliminating the need for a regulated power supply.
Filterless modulation allows the MAX9737 to pass CE
EMI limits with 1m cables using only a low-cost ferrite
bead and small-value capacitor on each output.
Comprehensive click-and-pop suppression circuitry
reduces noise on power-up/down or into and out of
shutdown or mute.
An input op amp allows the user to create a lowpass or
highpass filter, and select an optimal gain. The internal
precharge circuit ensures clickless/popless turn-on
within 10ms.
The MAX9737 is available in the 24-pin, TQFN-EP pack-
age and is specified over the -40°C to +85°C tempera-
ture range.
