Product Description

The SSM2518CPZ is a digital input stereo class-D Audio Power Amplifier that combines 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.
Serial digital audio interface supports common formats
I²C control interface or standalone operation
91% Efficiency at full scale into an 8R load
97dB Signal-to-noise ratio (SNR), A-weighted
80dB Power supply rejection ratio (PSRR) at 217Hz
-71.25dB to 24dB in 0.375dB steps Digital volume control
Supports a wide range of sample rates from 8 to 96kHz
Automatic sample rate detection
Pop-and-click suppression
Short-circuit and thermal protection with programmable auto recovery
Smart power-down when no input signal is detected
Power-on reset
Low power modes for performance/power trade-offs
User selectable ultralow EMI emission mode
Programmable dynamic range compression (DRC) with noise gate, expander, compressor and limiter
