DG189/190/191 High-Speed Drivers with Dual SPDT JFET Switches Features Benefits Applications Constant On-Resistance Over Entire Analog Range Low Leakage Low Crosstalk Rad Hardness Low Distortion Eliminates Large Signal Errors High Precision High Bandwidth Capability Fault Protection Audio Switching Video Switching Sample/Hold Guidance and Control Systems Aerospace Description The DG189/190/191 are precision dual single-pole, double-throw (SPDT) 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 (DG189--10 , DG190--30 , DG191--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. To achieve fast and accurate switch performance, each device comprises four n-channel JFET transistors and a TTL compatible bipolar driver. The driver is designed to achieve break-before-make switching action, eliminating the inadvertent shorting between channels and the crosstalk which would result. 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.
