The MAX9702 speaker amplifier offers two modulation schemes: a fixed-frequency (FFM) mode and a spreadspectrum (SSM) mode that reduces EMI-radiated emissions. The MAX9702 speaker amplifier features a fully differential architecture, full-bridged (BTL) output, and comprehensive click-and-pop suppression. The MAX9702 speaker amplifier features high 75dB PSRR, low 0.07% THD+N, and SNR in excess of 97dB. Shortcircuit and thermal-overload protection prevent the device from being damaged during a fault condition. The headphone amplifier uses Maxim's patented DirectDriveTM architecture that produces a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors, saving cost, board space, and component height. A high 80dB PSRR and low 0.02% THD+N ensures clean, low-distortion amplification of the audio signal. An I2C interface sets the speaker and headphone gain, mono, stereo, and mute functions. The MAX9702 is available in 28-pin thin QFN-EP (5mm x 5mm x 0.8mm) and 28-pin TSSOP packages. The MAX9702 is specified over the extended -40C to +85C temperature range.
