AK4204
Stereo Cap-less LINE-Amp and Video-Amp
GENERAL DESCRIPTION
The AK4204 is an audio stereo cap-less line driver with 1-channel video driver. It eliminates the need for
large DC-blocking capacitors with a built-in Charge-pump circuit. The AK4204 achieves 2Vrms outputs
with excellent linearity by single 3.3V power supply. It is well suitable for Blu-ray player and set-top box
systems. The AK4204 is available in small 16-pin TSSOP, saving the system space and cost.
