General Description

The APA2171 is a stereo, differential input, single supply, and cap-free line driver, which is available in SOP-14 and TSSOP-14 packages.

The APA2171 is ground-reference output, and doesn’t need the output capacitors for DC blocking. The advan tages of eliminating the output capacitor are saving the cost, eliminating component height, and improving the low frequency response.
