Product overview
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.
