Applications
The APA2172 is a stereo, differential input, single supply,
and cap-free line driver, which is available in SOP-14 and
TSSOP-14 packages.
The APA2172 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. APA2172 has shutdown
and under-voltage detector function for Depop solution.
The APA2172 is capable of driving 2.1Vrms at 3.3V into
2.5kΩ load, and provides short-circuit and thermal pro-
tection.
