The DG183/184/185 are precision dual double-pole,single-throw (DPST) analog switches designed to provide accurate switching of video and audio signals. This series is ideally suited for applications requiring a constant on-resistance over the entire analog range.
The major difference in the devices is the on-resistance (DG183-10 , DG184-30, DG185-75 ) Reduced errors are achieved through low leakage current (ID(on) < 2 nA). Applications which benefit from the flat JFET on-resistance include audio switching, video switching, and data acquisition.
