GENERAL DESCRIPTION

The SSM2518 is a digital input, Class-D power amplifier that com-

bines a digital-to-analog converter (DAC) and a sigma-delta

(Σ-Δ) Class-D modulator. This unique architecture enables

extremely low real-world power consumption from digital

audio sources with excellent audio performance. The SSM2518

is ideal for power sensitive applications, such as mobile phones

and portable media players, where system noise can corrupt

small analog signals such as those sent to an analog input audio

amplifier.

Using the SSM2518, audio data can be transmitted to the amplifier

over a standard digital audio serial interface, thereby significantly

reducing the effect of noise sources such as GSM interference or

other digital signals on the transmitted audio. The closed-loop

digital input design retains the benefits of an all digital amplifier,

yet enables very good PSRR and audio performance. The three

level, Σ-Δ Class-D modulator is designed to provide the least

amount of EMI interference, the lowest quiescent power dissi-

pation, and the highest audio efficiency without sacrificing

audio quality.

Input is provided via a serial audio interface, programmable to

accept all common audio formats including I2S and TDM. Control

of the IC is provided via an I2C control interface. The SSM2518

can accept a variety of input MCLK frequencies and can use

BCLK as the clock source in some configurations.

Additional features include a soft digital volume control, de-

emphasis, and a programmable digital dynamic range

compressor.

The architecture of the SSM2518 provides a solution that offers

lower power and higher performance than existing DAC plus

Class-D solutions. Its digital interface also offers a better system

solution for other products whose sole audio source is digital,

such as wireless speakers, laptop PCs, portable digital televisions,

and navigation systems.
