The APA2177 is a stereo, fixed gain, single supply, and
cap-free headphone driver, which is available in a WLCSP-
16 packages.
The APA2177 is ground-reference output, and no need
the output capacitors for DC blocking. The advantages of
eliminating the output capacitor are saving the cost, elimi-
nating component height, and improving the low frequency
response.
The internal selectable gain (0dB or 6dB) can minimize
the external component counts and save the PCB space.
High PSRR provides increased immunity to noise and
RF rectification.
The APA2177 is capable of driving 25mW at 3.6V into 16
load and provides thermal protection.

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 “Green” to 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).
