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 32Ω 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.
