1 / 31 page October 2010 Doc ID 17913 Rev 1 1/31 31 TS4604 Stereo headset driver and analog audio line driver with integrated reference to ground Features ■ Operating from VCC = 3 V up to 4.8 V single supply operation ■ Line driver stereo differential inputs ■ External gain setting resistors ■ Space-saving package: TSSOP28 pitch 0.65 mm ■ Dedicated shutdown control per function ■ 100 mW headset drive into a 16 Ω load ■ 90 dB high PSRR on headset drive ■ Two internal negative supplies to ensure ground-referenced, headset and line driver capless outputs ■ Internal undervoltage mute ■ Line driver 2 Vrms typ. Output voltage across entire supply voltage range ■ Pop-&-click reduction circuitry, thermal shutdown and output short-circuit protection Applications ■ PDP/LCD TV ■ Set-top boxes Description The TS4604 is a stereo ground-referenced output analog line driver and stereo headset driver whose design allows the output DC-blocking capacitors to be removed, thus reducing component count. The TS4604 drives 2 Vrms into a 5 k Ω load or more. The device has differential inputs and uses external gain setting resistors. The TS4604 delivers up to 100 mW per channel into a 16 Ωload. All outputs of the TS4604 include ±8 kV human body model ESD protection cells. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 28 27 26 25 24 23 22 21 20 19 18 17 16 15 +LDL -LDL OUTLDL AGND ENLD PVSSLD CNLD CNHP PVSSHP ENHP AGND OUTHPL -HPL +HPL +HPR -HPR OUTHPR NC PGND PVCCHP CPHP CPLD PVCCLD PGND EUVP OUTLDR -LDR +LDR TSSOP28 Pin connections (top view) www.st.com |
