GENERAL DESCRIPTION
The SSM2517 is a PDM digital input Class-D power amplifier that offers higher performance than existing DAC plus Class-D solutions. The SSM2517 is ideal for power sensitive applications, such as mobile phones and portable media players, where system noise can corrupt the small analog signal sent to the amplifier.

FEATURES
   Filterless digital Class-D amplifier
   Pulse density modulation (PDM) digital input interface
   2.4 W into 4 Ω load and 1.38 W into 8 Ω load at 5.0 V supply
      with <1% total harmonic distortion plus noise (THD + N)
   Available in 9-ball, 1.5 mm × 1.5 mm, 0.5 mm pitch WLCSP
   92% efficiency into 8 Ω at full scale
   Output noise: 43 μV rms at 3.6 V, A-weighted
   THD + N: 0.035% at 1 kHz, 100 mW output power
   PSRR: 85 dB at 217 Hz, input referred with dither input
   Quiescent power consumption: 10.4 mW
      (VDD = 1.8 V, PVDD = 3.6 V, 8 Ω + 33 μH load)
   Pop-and-click suppression
   Configurable with PDM pattern inputs
   Short-circuit and thermal protection with autorecovery
   Smart power-down when PDM stop condition
      or no clock input detected
   64 × fS or 128 × fS operation supporting 3 MHz and 6 MHz clocks
   DC blocking high-pass filter and static input dc protection
   User-selectable ultralow EMI emissions mode
   Power-on reset (POR)
   Minimal external passive components

APPLICATIONS
   Mobile handsets
