General Description
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.
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 fil-
terless 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 mod-
ulation is optimized for best audio performance when
using a full LC filter.
A pin-selectable stereo/mono mode allows stereo oper-
ation 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.
Comprehensive click-and-pop reduction circuitry mini-
mizes noise coming into and out of shutdown or mute.
Input op amps allow the user to create summing amplifiers,
lowpass or highpass filters, and select an optimal gain.
The MAX9736A/B/D are available in 32-pin TQFN pack-
ages and specified over the -40°C to +85°C tempera-
ture range.
