TD9722

Techcode® Stereo, Differential Input Cap-Free Line Driver DATASHEET TD9722 General Description Features The TD9722 is a stereo, differential input, single supply,and cap-free line driver, which is available in SOP-14 and TSSOP-14 packages. The TD9722 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. TD9722 has shutdown and under-voltage detector function for Depop solution. The TD9722 is capable of driving 2.1Vrms at 3.3V into 2.5kload, and provides short-circuit and thermal rotection.  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 < 8uVrms - THD+N < 0.02% at 20Hz~20kHz  Output Voltage Swing Can Reach 2.1Vrms/Ch into2.5kΩ at VDD=3.3V  High PSRR: 80dB at 217Hz  Fast Start-up Time: 500us  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) Applications  Set-Top Boxes  CD/DVD Players  LCD TVs  HTIBs (Home Theater in Box) October, 20...
