Description
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.
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.
The major difference in the devices is the on-resistance
(DG183—10 , DG184—30 , DG185—75 Reduced
errors are achieved through low leakage current (ID(on)
< 2 nA). Applications which benefit from the flat JFET
