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 (DG189—10 W , DG190—30 W , DG191—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. FUNCTIONAL BLOCK DIAGR...
