APA2171

APA2171 Stereo, Differential Input Cap-Free Line Driver Features General Description  Operating Voltage: 3V~3.6V  Differential Input  Ground Reference Output - No Output Capacitor Required (for DC Blocking) - Save the PCB Space - Reduce the BOM Costs - Improve the Low Frequency Response  Low Noise and THD+N - SNR > 108dB - Noise < 8mVrms - THD+N < 0.02%at 20Hz~20kHz  Output Voltage Swing Can Reach 2.1Vrms/Ch into 2.5kΩ at VDD=3.3V  High PSRR: 80dB at 217Hz  Fast Start-up Time: 500ms  Integrate the De-Pop Circuitry  Thermal and Short-Circuit Protection  Surface-Mount Packaging - SOP-14 - TSSOP-14  Lead Free and Green Devices Available (RoHSCompliant) 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.
