DG183/184/185 High-Speed Drivers with Dual DPST JFET Switches Features Benefits Applications Constant On-Resistance Over Entire Analog Range Low Leakage Low Crosstalk Break-Before-Make Switching Rad Hardness Low Distortion Eliminates Large Signal Errors High Precision Improved Channel Isolation Eliminates Inadvertent Shorting Between Channels Fault Protection Audio Switching Precision Switching Video Switching Video Routing Sample/Hold Aerospace 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. 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. 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).
