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-
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.
