MAX9712 500mW, Low EMI, Filterless, Class D Audio Amplifier

The MAX9712 mono class D Audio Power Amplifier provides class AB Amplifier performance with class D efficiency, conserving board space, and extending battery life. Using a class D architecture, the MAX9712 delivers up to 500mW into an 8 load while offering efficiencies above 85%. A patented, low EMI modulation scheme renders the traditional class D output Filter unnecessary.
The MAX9712 offers two modulation schemes: a fixedfrequency (FFM) mode, and a spread-spectrum (SSM) mode that reduces EMI-radiated emissions due to the modulation frequency. Furthermore, the MAX9712 Oscillator CAN be synchronized to an external Clock through the SYNC input, allowing the switching frequency to be user defined. The SYNC input also allows multiple MAX9712s to be cascaded and frequency locked, minimizing interference due to Clock intermodulation. The device utilizes a fully differential architecture, a fullbridged output, and comprehensive click-and-pop suppression. The gain is internally set to +4V/V, further reducing external component count.
The MAX9712 features high 72dB PSRR, a low 0.01% THD+N, and SNR in excess of 90dB. Short-circuit and thermal-overload protection prevent the device from damage during a fault condition. The MAX9712 is available in 10-pin TDFN (3mm x 3mm x 0.8mm), 10-pin MAX, and 12-bump UCSP (1.5mm x 2mm x 0.6mm) packages. The MAX9712 is specified over the extended -40C to +85C temperature range.
