APA2172

APA2172 Stereo, Differential Input Cap-Free Line Driver Features General Description 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 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. 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 protection. Operating Voltage: 2.3V~5.5V 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 < 8µVrms - 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: 500µs Integrate the De-Pop Circuitry Thermal and Short-Circuit Protection Surface-Mount Packaging - SOP-14 - TSSOP-14 Lead Free and Green Devices Available (RoHS Compliant) Simplified Application Circuit Applications Stereo Input Signal APA2172 Stereo Line-Out Signal ...
