The TK15210M is an Analog Switch IC that was developed for audio frequency applications. The function of the IC is to select one output from two input channels. The channel selection is controlled by a low level. The TK15210M operates from a single power supply with the input bias built-in (VCC/2). Because the distortion is very low, the TK15210M is suitable for various signal switching applications, especially Hi-Fi devices. The TK15210M offers a wide operating voltage range with simple associated circuitry.
