DG300B, DG301B, DG302B, DG303B
Vishay Siliconix
CMOS Analog Switches
DESCRIPTION
FEATURES
The DG300B, DG303B family of monolithic CMOS switches Analog signal range: 15 V
feature three switch configuration options (SPST, SPDT,
Fast switching - t : 150 ns
ON
and DPST) for precision applications in communications,
Low on-resistance - R : 30
DS(on)
instrumentation and process control, where low leakage
Single supply operation
switching combined with low power consumption are
Latch-up proof
required.
CMOS compatible
Designed on the Vishay Siliconix PLUS-40 CMOS process,
these switches are latch-up proof, and are designed to block
BENEFITS
up to 30 V peak-to-peak when off. An epitaxial layer prevents
latchup.
Full rail-to-rail analog signal range
In the on condition the switches conduct equally well in both
Low signal error
directions (with no offset voltage) and minimize error
Low power dissipation
conditions with their low on-resistance.
Featuring low power consumption (3.5 mW typ.) these
APPLICATIONS
switches are ideal for battery powered applications,
Low level switching circuits
without sacrificing switching speed. Designed for
Programmable gain amplifiers
break-before-make switching action, these devices are
Portable and battery powered systems
CMOS and quasi TTL compatible. Single supply operation is
allowed by connecting the V- rail to 0 V.
