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).
