The SSM2380 is a fully integrated, filter‑less, stereo Class‑D audio amplifier designed for mobile and portable electronics. It delivers up to 2 W into a 4 Ω load with high efficiency, low distortion and configurable I2C control for gain, ALC and EMI modes.
The handbook includes features, applications, detailed specifications, pin configuration, I2C timing, register maps, typical performance curves, layout guidelines and protection information, helping designers integrate the device into their products.
| Output Power (8 Ω, 5 V) | 1.43 W |
|---|---|
| Efficiency (normal, low EMI mode) | 93 % |
Gain is set via the I2C interface and can be selected from 1 dB to 24 dB (plus mute) in 47 steps without external components.
It provides short‑circuit and thermal protection, as well as pop‑and‑click suppression circuitry.
The shutdown register bits (STDNR for right channel, STDNL for left channel) control channel power‑down via I2C commands.
