TK15323 Audio Analog Switch FEATURES s s s s s Wide Operating Voltage Range (3 to 14 V) Low Distortion (typ. 0.003%) Wide Dynamic Range (typ. 6 VP-P) Low Output Impedance (typ. 20 Ω) Low Switching Noise (typ. 3 mV) APPLICATIONS s Audio Systems s Radio Cassettes DESCRIPTION The TK15323M 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 low level. The TK15323M has a mono-power supply and the input bias is a supply type from outside. Because the distortion is very low, the TK15323M fits various signals switching. It is best suited for Hi-Fi devices. Operating voltage is wide, the circuit plan is simple. The TK15323M is available in a small plastic surface mount package (SSOP-12).
