Docket:
Filterless, High Efficiency, Mono 2.5 W Class-D Audio Amplifier SSM2377
FEATURES
Filterless, Class-D amplifier with spread-spectrum - modulation 2.5 W into 4 load and 1.4 W into 8 load at 5.0 V supply with <1% total harmonic distortion plus noise (THD + N) 92% efficiency at 5.0 V, 1.4 W into 8 speaker >100 dB signal-to-noise ratio (SNR) High PSRR at 217 Hz: 80 dB Ultralow EMI emissions Single-supply operation from 2.5 V to 5.5 V Gain select function: 6 dB or 12 dB Fixed input impedance of 80 k 100 nA shutdown current Short-circuit and thermal protection with autorecovery Available in a 9-ball, 1.2 mm Ч 1.2 mm WLCSP Pop-and-click suppression
The SSM2377 operates with 92% efficiency at 1.4 W into 8 from a 5.0 V supply and has an SNR of >100 dB.

Spread-spectrum pulse density modulation (PDM) is used to provide lower EMI-radiated emissions compared with other Class-D architectures. The inherent randomized nature of spread-spectrum PDM eliminates the clock intermodulation (beating effe
