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 kΩ 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 Ω load. All outputs of the TS4604 include

±8 kV human body model ESD protection cells.
