The DG186/187/188 are precision 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

data acquisition.
To achieve fast and accurate switch performance, each device
comprises two n-channel JFET transistors and a TTL
compatible bipolar driver. The driver is designed to achieve

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.
