DESCRIPTION
The DG5043 solid state analog switch is recommended for
general purpose applications in instrumentation, and process
control. Built on the Vishay Siliconix PLUS-40 high voltage
CMOS process, this device provides ease-of-use and
performance advantages to the system designer. Key
performance features of the DG5043 are 1-ms switching, low
power supply requirements, and break-before-make
switching. Each switch conducts equally well in either
direction, when on, and blocks up to 30 V peak-to-peak when
off. Off leakage current is 1-nA maximum. An epitaxial layer
prevents latch up. For new designs, DG403 is recommended.
