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.
PRODUCT HIGHLIGHTS
1.
2.
3.
4.
Very low on resistance, 0.5 Ω typical.
1.8 V to 5.5 V single-supply operation.
High current carrying capability.
Tiny 6-lead SOT-23, 8-lead MSOP, and 6-ball, 1.14 mm ×
2.18 mm WLCSP packages.
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.

Off time or on time measured between the 90% points of both
switches when switching from one address state to another.
Charge Injection
A measure of the glitch impulse transferred from the digital
input to the analog output during switching.
Channel-to-Channel Crosstalk
A measure of unwanted signal coupled through from one
channel to another as a result of parasitic capacitance.
Off Isolation
A measure of unwanted signal coupling through an off switch.
Bandwidth
Frequency at which the output is attenuated by −3 dB.
