DESCRIPTION
The DG2018 and DG2019 are low voltage, single supply
analog switches. The DG2018 is dual
double-pole/double-throw (DPDT) with two control inputs that
each controls a pair of single-pole/double-throw (SPDT). The
DG2019 uses one control pin to operate four independent
SPDT switches.
performance switching of analog signals; providing low
on-resistance (6 W @ +2.7 V), fast speed (Ton, Toff @ 42 ns
and 16 ns), and a bandwidth that exceeds 150 MHz.
a
The DG2018 and DG2019 were designed to offer solutions
that extend beyond audio/video functions, to providing the
performance required for today’s demanding mixed-signal
switching in portable applications.
When operated on a +3-V supply, the DG2018’s control pins
are compatible with 1.8-V digital logic. The DG2019 has an
available feature of a VL pin that allows a 1.0-V threshold for the
control pin when VL is powered with 1.5 V.
An epitaxial layer prevents latch-up. Brake-before-make is
guaranteed for all SPDT’s. All switches conduct equally well in
both directions when on, and blocks up to the power supply
level when off.
Built on Vishay Siliconix’s low voltage submicron CMOS
process, the DG2018 and DG2019 are ideal for high
