Applications
The APA2018 is a mono, high efficiency, filter-free
Class-D audio amplifier and is available in WLCSP1.5x2-
12 and TQFN4x4-16 Package.
The APA2018 is a high efficiency Class-D audio power
amplifier with an integrated Class-G boost converter that
enhances efficiency at low output power. It drives up to 3.
6W into an 4speaker (1%THD+N).With 85% typical
efficiency, the APA2018 helps extend battery life when play-
ing audio.
The built-in boost converter generates a 5.75V supply
voltage for the Class-D amplifier when high output power
is required. This provides a louder audio output than a
stand-alone amplifier directly connected to the battery.
During low audio output power periods, the boost con-
verter deactivates and connects VBAT directly to the Class-
D amplifier supply, PVDD. This improves overall efficiency.
The APA2018 has an integrated low-pass filter to improve
the RF rejection and reduce DAC out-of-band noise, in-
creasing the signal-to-noise ratio(SNR).

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines Greento mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
