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 kΩ load or more. The device has differential inputs and uses external gain setting resistors.

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
