Sample-and-Hold
The DG201A_MIL and DG202_MIL are quad SPST analog
switches designed to provide accurate switching over a wide
range of input signals. When combining a low on-resistance
and a wide signal range (15 V) with low charge-transfer
these devices are well suited for industrial and military
applications.
switches will block up to 30 V peak-to-peak and have a 44-V
absolute maximum power supply rating.
Built on Vishay Siliconix’ high voltage metal gate process to
achieve optimum switch performance, each switch conducts
equally well in both directions when on. When off these
The DG201A_MIL/202_MIL are available in hermetic
packages. For plastic packages, use the DG201B/202B as
pin-for-pin replacements.
These two devices are differentiated by the type of switch
actions (See Truth Table).
