DESCRIPTION
The
double-throw (SPDT) analog switches designed to provide
accurate switching of video and audio signals. This series is
ideally
on-resistance over the entire analog range.
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 (I
< 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. The driver is designed to achieve
break-before-make
inadvertent shorting between channels and the crosstalk
which would result. 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.
