APA2173 Datasheet | ANPEC

Features General Description - Operating Voltage: 2.3V~5.5V The APA2173 is a stereo, differential input, single supply, - Differential Input and cap-free line driver, which is available in MSOP-10P - Ground Reference Output package. - No Output Capacitor Required (for DC Blocking) The APA2173 is ground-reference output, and doesn’t - Save the PCB Space need the output capacitors for DC blocking. The advan- - Reduce the BOM Costs tages of eliminating the output capacitor are saving the - Improve the Low Frequency Response cost, eliminating ponent height, and improving the - Low Noise and THD+N low frequency response. The external gain setting is remended using from - SNR > 108d B ±1V/V to ±10V/V. High PSRR provides increased immu- - Noise < 8µVrms nity to noise and RF rectification. APA2173 has shutdown - THD+N < 0.02% at 20Hz~20k Hz and under-voltage detector function for Depop solution. - Output Voltage Swing Can Reach 2.1Vrms/Ch into The APA2173 is capable of driving 2.1Vrms at 3.3V into 2.5kΩ at VDD=3.3V 2.5kΩ load, and provides short-circuit and thermal pro- - High PSRR: 80d B at 217Hz tection. - Fast Start-up Time: 500µs - Integrate the De-Pop Circuitry - Thermal and Short-Circuit Protection Simplified Application Circuit - Surface-Mount Packaging -MSOP-10P - Lead Free and Green Devices Available (Ro HS pliant) Applications - Set-Top Boxes - CD/DVD Players - LCD TVs - HTIBs (Home Theater in Box) Stereo Input Signal Stereo Line-Out Signal ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise customers to obtain the latest version of relevant information to verify before placing orders.
