GENERAL DESCRIPTION
The ADG819 is a monolithic, CMOS, single-pole, double-throw
(SPDT) switch. This switch is designed on a submicron process
that provides low power dissipation yet gives high switching
speed, low on resistance, and low leakage currents.
Low power consumption and an operating supply range of
1.8 V to 5.5 V make the ADG819 ideal for battery-powered,
portable instruments.
Each switch of the ADG819 conducts equally well in both
directions when on. The ADG819 exhibits break-before-make
switching action, thus preventing momentary shorting when
switching channels.
The ADG819 is available in a 6-lead SOT-23 package, an 8-lead
MSOP package, and in a 6-ball WLCSP package. This chip
occupies only a 1.14 mm × 2.18 mm area, making it the ideal
candidate for space-constrained applications.
