General Description
The MAX9722A/MAX9722B stereo headphone amplifiers are designed for portable equipment where board space is at a premium.

The MAX9722A/MAX9722B use a unique DirectDrive architecture to produce a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors, which saves cost, board space, and component height. Additionally, the gain of the amplifier is set internally (-2V/V, MAX9722B) or adjusted externally (MAX9722A). The MAX9722A/MAX9722B deliver up to 70mW per channel into a 16 load or 130mW into a 32 load and have low 0.009% THD+N. An 80dB at 217Hz power-supply rejection ratio (PSRR) allows these devices to operate from noisy digital supplies without an additional linear regulator. The MAX9722A/MAX9722B include ±8kV ESD protection on the headphone outputs. Comprehensive anticlick-and-pop cir
