TK15220 Audio Analog Switch FEATURES s s s s s Wide Operating Voltage Range (2 to 13 V) Low Distortion (typ. 0.004%) Wide Dynamic Range (typ. 6 VP-P) Low Output Impedance (typ. 20 Ω) Protection at Output Terminal. APPLICATIONS s Audio Systems s Radio Cassettes DESCRIPTION The TK15220M 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 can be controlled by a higher level by the addition of an external resistor. The TK15220M operates from a single power supply with the input bias built-in (VCC/2). Because the distortion is very low, the TK15220M is suitable for various signal switching applications, especially Hi-Fi devices. The TK15220M offers a wide operating voltage range with simple associated circuitry. The TK15220M is available in the small SOT23L-6 plastic surface mount package.
