DESCRIPTION
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. on-resistance include audio switching, video switching, and data acquisition.
The major difference in the devices is the on-resistance (DG183--10 W, DG184--30 W, DG185--75 W). Reduced errors are achieved through low leakage current (ID(on) < 2 nA). Applications which benefit from the flat JFET
To achieve fast and accurate switch performance, each device comprises four n-channel JFET transistors and a TTL compatible bipolar driver. In the on state, each switch conducts current equally well in either direction. In the off condition, the switches will block up to 20 V peak-to-peak, with feedthrough of less than -60 dB at 10 MHz.
