MAX9736BETJ+

The MAX9736BETJ+ is a mono/stereo high power class D amplifier in 32 pin TQFN package. It provides high performance, thermally efficient amplifier solutions. The MAX9736B output 2x6W in stereo mode and 12W in mono mode. It features a pin-selectable modulation schemes that select between filterless spread spectrum switching mode or a classic PWM fixed frequency switching mode. Filterless modulation allows the device to pass CE EMI limits with 1m cables using a low cost ferrite bead and capacitor on each output. Classic PWM modulation is optimized for best audio performance when using a full LC filter. A pin-selectable stereo/mono mode allows stereo operation into 8ohm loads or mono operation into 4ohm loads. In mono mode, the right input op-amp becomes available as a spare device allowing flexibility in system design. The gain is set externally set and operates in low power shutdown mode. Comprehensive click and pop circuitry minimizes noise into and out of shutdown or mute.

• Supply voltage range is 8V to 28V
• Operating temperature range from -40°C to 85°C
• Quiescent supply current is 14mA and shutdown current is 1μA
• High 67dB PSRR at 1KHz eliminating the need for a regulated power supply
• Efficiency is 88% at 12V supply
• Thermal and output current protection
• Low power shutdown mode reduces supply current to less than 1μA
• 0.04% of THD+N
• Input op-amps allow user to create summing amplifiers, lowpass/highpass filter & select optimal gain
