KIT ATION EVALU E AILABL AV
Stereo Headphone Amplifier with BassMax, Volume Control, and Input Mux
General Description
The MAX9729 stereo DirectDriveTM headphone amplifier features bass boost, volume control, an input mux, and an I2C/SMBusTM-compatible serial interface.

This makes the MAX9729 ideal for portable audio applications where space is at a premium and performance is essential. The MAX9729 operates from a single 1.8V to 3.6V, and uses Maxim's patented DirectDrive architecture, eliminating the need for large DC-blocking capacitors. The headphone amplifiers deliver 52mW into a 32 load, feature low 0.03% THD+N, and high 90dB PSRR. Maxim's industry-leading click-and-pop suppression circuitry reduces audible transients during power and shutdown cycles. The BassMax feature boosts the bass response of the amplifier, improving audio reproduction for low-end headphones. The integrated volume control features 32 discrete volume levels along with a ramping function
