DG447/448
Vishay Siliconix
Low Power, High Voltage SPST Analog Switches
DESCRIPTION
The DG447 and DG448 are dual supply single-pole/single-
throw (SPST) switches. On resistance is 25 Ω maximum and
flatness is 2.2 Ω max over the specified analog signal range.
These analog switches were designed to provide high
speed, low error switching of precision analog signals. The
primary application areas are in the routing and switching in
telecommunications and test equipment. Combining low
power, low leakages, low on-resistance and small physical
size, the DG477/448 are also ideally suited for portable and
battery powered industrial and military equipment.
The DG477 has one normally closed switch, while the
DG448 switch is normally open. They operate either from a
single + 7 V to 36 V supply or from dual ± 4.5 V to ± 20 V
supplies. They are offered in the very popular, small
T6SOP6 package.
