Description
The DG201A and DG202 are quad SPST analog switches conducts equally well in both directions when on. When off
designed to provide accurate switching over a wide range these switches will block up to 30 V peak-to-peak and have
of input signals. When combining a low on-resistance and a 44-V absolute maximum power supply rating.
a wide signal range ("15 V) with low charge-transfer these
devices are well suited for industrial and military
applications.
These two devices are differentiated by the type of switch
actions (See Truth Table).
Built on Siliconix’ high voltage metal gate process to The DG201B/DG202B upgrades are recommended for new
