Overview
Filterless, High Efficiency, Mono 3 W Class-D Audio Amplifier SSM2319 FEATURES Filterless Class-D amplifier with ultraefficient spreadspectrum Σ-Δ modulation Internal modulator synchronization (SYNC) 3 W into 3 Ω load and 1.
4 W into 8 Ω load at 5.
0 V supply with <1% total harmonic distortion (THD) 90% efficiency at 5.
0 V, 1.
4 W into 8 Ω speaker Signal-to-noise ratio (SNR): 98 dB Single-supply operation: 2.
5 V to 5.
5 V Ultralow shutdown current: 20 nA Short-circuit and thermal protection with autorecovery Available in 9-ball, 1.
5 mm × 1.
5 mm WLCSP Pop-and-click suppression Built-in resistors reduce board component count Default fixed 12 dB or user-adjustable gain setting The SSM2319 features a high efficiency, low noise modulation scheme that does not require any external LC output filters.
The modulation continues to provide high efficiency even at low output power.
It operates with 90% efficiency at 1.
4 W into 8 Ω or 85% efficiency at 3 W into 3 Ω from a 5.
0 V supply and has...
