The SSM2529 is a digital input, Class-D power amplifier that combinesa digital-to-analog converter (DAC), a low power audio specificdigital signal processor, and a sigma-delta (Σ-Δ) Class-D modulator.
This unique architecture enables extremely low real-world powerconsumption from digital audio sources with excellent audioperformance. The SSM2529 is ideal for power sensitive applications,such as mobile phones and portable media players, where systemnoise can the corrupt small analog signals that are sent to ananalog input audio amplifier.
Using the SSM2529, audio data can be transmitted to the amplifierover a standard digital audio serial interface, thereby significantlyreducing the effect of noise sources such as GSM interference orother digital signals on the transmitted audio. The closed-loopdigital input design retains the benefits of an all-digital amplifier, yetenables very good PSRR and audio performance. The three-level,Σ-Δ Class-D modulator is designed to provide the least amount ofEMI, the lowest quiescent power dissipation, and the highestaudio efficiency without sacrificing audio quality.
The audio input is provided via a serial audio interface that can beprogrammed to accept all common audio formats, including I2S,TDM, and PDM. Control of the IC is provided via an I2C controlinterface. An alternative to I2C control is standalone operationmode, which allows several settings that are adjusted by off-chipexternal resistors. The SSM2529 can accept a variety of input MCLKfrequencies and can use BCLK as the clock source in someconfigurations. An integrated PLL can also provide the devicemaster clock.
The integrated DSP includes soft digital volume control circuits; ade-emphasis, high-pass filter; a seven-band programmable equalizer;and a programmable digital dynamic range compressor. In addition,the part includes a feedforward speaker temperature predictionmodule to protect the loudspeaker.
The SSM2529 supports single-supply mode, where DVDD isprovided by the on-chip LDO regulator, eliminating the need for anexternal digital core supply.
The digital interface is very flexible and convenient. It can offer abetter system solution for other products whose sole audio sourceis digital, such as wireless speakers, laptop PCs, portable digitaltelevisions, and navigation systems.
The SSM2529 is specified over the industrial temperature range of−40°C to +85°C. It has built-in thermal shutdown and output shortcircuitprotection. It is available in a 16-ball, 1.92 mm × 1.94 mmwafer level chip scale package (WLCSP).
