TK15328 Audio Analog Switch FEATURES s s s s s s Wide Operating Voltage Range (±2 to ±7 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) Output Parallel Connection Possible APPLICATIONS s Audio Systems s Radio Cassettes DESCRIPTION The TK15328M is an Analog Switch IC that was developed for audio frequency. Function is to select one output from two inputs, and has floating position too. The channel can be changed by two control levels and in a device that includes two circuits. The TK15328M has a dual power supply and the input bias is direct coupling at GND level. Because the distortion is very low, the TK15328M fits various signals switching. It is best suited for Hi-Fi devices. Operating voltage is wide, the circuit plan is simple. The TK15328M is available in a small plastic surface mount package (SSOP-12).
