The TK15326M is an Analog Switch IC that was developed for audio frequency. Function is to select one output from two inputs in a device that includes two circuits, and the channel can be changed by high level. The TK15326M has a dual power supply and the input bias is direct coupling at GND level. Because the distortion is very low, the TK15326M fits various signals switching. It is best suited for Hi-Fi devices. Operating voltage is wide, the circuit plan is simple. The TK15326M is available in a small plastic surface mount package (SSOP-12).
