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.
The major difference in the devices is the on-resistance

< 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.
