Intended for cell phones, the MAX9775/MAX9776 Class D audio subsystems provide 3-D stereo enhancement. Both are designed around the company’s technologies, specifically spread-spectrum modulation, Active Emissions Limiting (AEL), Class D filterless amps, and DirectDrive Technology.
The MAX9775 integrates five output amplifiers: a mono, DirectDrive, 80-mW receiver amplifier, a stereo, DirectDrive, 80-mW headphone amplifier, and a Class D, stereo 1.5-W audio power amplifier. The MAX9776 has four output amplifiers: the mono, 80-mW receiver amplifier, the stereo, DirectDrive 80-mW headphone amplifier, and a mono Class D amplifier. Both are housed in 32-pin TQFN packages and exhibit greater than 70% efficiencies. (ea/10,000, MAX9775, $1.45; MAX9776, $1.25—available now.)
