General Description
The APA2180,APA2180 is a stereo, fixed gain, single supply, and
cap-free headphone driver, which is available in a
WLCSP1.6x1.6-12and TDFN3x3-12 packages.
The APA2180 is ground-reference output and don’t 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 fixed gain setting (-1.5V/V) can minimize the
external component counts and save the PCB space. High
PSRR provides increased immunity to noise and RF
rectification.
The APA2180 is capable of driving 50mW at 3.6V into 16Ω
load and provides thermal protection.
