the dg180/181/182 are precision dual single-pole, single-throw (spst) 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 (dg180e10 , dg181e30 , dg182e75 reduced errors are achieved through low leakage current (i d(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. 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.
