G3208 Global Mixed-mode Technology Inc. Dual 0.75Ω SPDT Analog Switch Features General Description The G3208 is a low on-resistance, dual channel SPDT (Single-Pole/Double-Throw) analog switch that operates from a 2.25V to 5.5V supply. The device offers an excellent ON-resistance matching, and low total harmonic distortion (THD) performance. The device is designed for fast switching speeds with the breakbefore-make feature to prevent signal distortion during the transferring of signal from one channel to another. These features make this device suitable for portable audio applications. The G3208 has a separate logic supply pin (VIO) that is characterized to operate from 1.65V to 1.95V. VIO powers the control circuitry, which allows the G3208 to be controlled by 1.8V signals.
