General Description
The APA2175 is a stereo, fixed gain, single supply, and cap-free line driver, which is available in TQFN4x4-20B and TSSOP-16 packages.
The APA2175 is ground-reference output, and no need the output capacitors for DC blocking. The advantages of eliminating the output capacitor are saving the cost, eliminating component height, and improving the low frequency response.
