SSM2537

Data Sheet PDM Digital Input, Mono 2.7 W Class-D Audio Amplifier SSM2537 FEATURES architecture enables extremely low real-world power consumption Filterless digital Class-D amplifier Pulse density modulation (PDM) digital input interface 2.7 W into 4 Ω load and 1.4 W into 8 Ω load at 5.0 V supply with <1% total harmonic distortion plus noise (THD + N) Available in 9-ball, 1.2 mm × 1.2 mm, 0.4 mm pitch WLCSP 93% efficiency into 8 Ω at full scale Output noise: 25 µV rms at 3.6 V, A-weighted from digital audio sources with excellent audio performance. Using the SSM2537, audio can be transmitted digitally to the audio amplifier, significantly reducing the effect of noise sources such as GSM interference or other digital signals on the transmitted audio. The SSM2537 is capable of delivering 2.7 W of continuous output power with <1% THD + N driving a 4 Ω load from a 5.0 V supply. THD + N: 0.005% at 1 kHz, 100 mW output power The SSM2537 features a high efficiency, low noise mod...
