The SSM2377 is a filterless, high efficiency, mono 2.5 W Class-D audio amplifier. It features high efficiency, high signal-to-noise ratio, and low electromagnetic emissions.
The SSM2377 is a fully integrated, filterless Class‑D audio amplifier designed for mobile phones and portable electronics. It delivers up to 2.5 W continuous output with 92 % efficiency, >100 dB SNR, and ultralow EMI emissions.
The handbook includes features, applications, functional block diagram, detailed specifications, absolute maximum ratings, pin configuration, typical performance curves, layout recommendations, and ordering information, giving designers all the data needed to implement the device.
| Efficiency (1.4 W into 8 Ω, 5 V) | 92.4 % |
|---|---|
| Shutdown Current | 100 nA |
It reduces output voltage transients when the shutdown pin is toggled, limiting audible pops to as low as 10 mV.
The shutdown current is typically 100 nA.
