Low RF Susceptibility DirectDrive Stereo Headphone Amplifier with 1.8V Compatible Shutdown
General Description
The MAX9724C/MAX9724D stereo headphone amplifiers are designed for portable equipment where board space is at a premium. These devices use a unique, DirectDriveŽ architecture to produce a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors, saving cost, board space, and component height. The MAX9724 suppresses RF radiation received by input and supply traces acting as antennas and prevents the amplifier from demodulating the coupled noise. The MAX9724C offers an externally adjustable gain while the MAX9724D has an internally preset gain of -1.5V/V. The MAX9724C/MAX9724D deliver up to 60mW per channel into a 32 load and have low 0.02% THD+N. An 80dB at 1kHz power-supply rejection ratio (PSRR) allows these devices to operate from noisy digital supplies without an additional linear regulator. Comprehensive cli
