APA2718 Overview
The APA2178 is a stereo, fixed gain, Cap-Free headphone driver which is available in a WLCSP2x2-16 package. The APA2178 is a ground-reference output, and doesn’ t need the output capacitors for DC blocking. The advantages of eliminating the output capacitor are saving the cost, PCB’ s space, and ponent height.
