2 W into 8 Ω at 5.
0 V supply with less than 10% THD 85% efficiency at 5.
0 V, 2W into 4 Ω speaker Better than 95dB SNR (signal-to-noise ratio) Available in 16-lead 3 mm × 3 mm LFCSP Single-supply operation from 2.
2 V to 5.
0 V 20 nA ultralow shutdown current Short-circuit and thermal protection Pop-and-click suppression Built-in resistors reduce board component count Default fixed 18dB gain and user-adjustable 2 W Filterless Class-D Stereo Audio Amplifier SSM2304 The SSM2304 features a high efficiency, low noise modulation scheme.
It operates with 85% efficiency at 2 W into 4 Ω from a 5.
0 V supply and has a signal-to-noise ratio (SNR) that is better than 95 dB.
PDM modulation is used to provide lower EMIradiated emissions compared with other Class-D architectures.
The SSM2304 has a micropower shutdown mode with a typical shutdown current of 20 nA.
