APA2171
Active
Stereo, Differential Input Cap-Free Line Driver
Features
- Save the PCB Space
- Reduce the BOM Costs
- Improve the Low Frequency Response
- Noise < 8µVrms
- THD+N < 0.02% at 20Hz~20kHz
- TSSOP-14
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 advantages 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 immunity 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 2.5kΩ load, and provides short-circuit and thermal protection.
