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 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 on-resistance include audio switching, video switching, and data acquisition. To achieve fast and accurate switch performance, each device prises four n-channel JFET transistors and a TTL patible 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.
