DG611, DG612, DG613
Vishay Siliconix
High-Speed, Low-Glitch D/CMOS Analog Switches
DESCRIPTION
The DG611, DG612, DG613 feature high-speed low-
capacitance lateral DMOS switches. Charge injection has
been minimized to optimize performance in fast sample-and-
hold applications.
Each switch conducts equally well in both directions when on
and blocks up to 16 V
p-p
when off. Capacitances have been
minimized to ensure fast switching and low-glitch energy. To
achieve such fast and clean switching performance, the
DG611, DG612, DG613 are built on the Vishay Siliconix
proprietary D/CMOS process. This process combines
n-channel DMOS switching FETs with low-power CMOS
control logic and drivers. An epitaxial layer prevents latchup.
The DG611 and DG612 differ only in that they respond to
opposite logic levels. The versatile DG613 has two normally
open and two normally closed switches. It can be given
various configurations, including four SPST, two SPDT, one
DPDT.
