Stereo Cap-less LINE-Amp and Video-Amp
The AK4203 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 AK4203 achieves 2Vrms outputs with excellent linearity 2Vrms output by single 3.3V power supply. The AK4203 is available in small 16-pin TSSOP, saving the system space and cost.
