Applications
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.
The external gain setting is recommended using from
±1V/V to ±10V/V. High PSRR provides increased immu-
nity to noise and RF rectification. APA2171 has shutdown
and under-voltage detector function for Depop solution.
The APA2171 is capable of driving 2.1Vrms at 3.3V into
2.5kload, and provides short-circuit and thermal pro-
tection.

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).

Note1: Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are
stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recom-
mended operating conditions" is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device
reliability.
