GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The ADG419 is a monolithic CMOS SPDT switch. This
switch is designed on an enhanced LC2MOS process that pro-
vides low power dissipation yet gives high switching speed, low
on resistance and low leakage currents.
1. Extended Signal Range
The ADG419 is fabricated on an enhanced LC2MOS pro-
cess, giving an increased signal range that extends to the
supply rails.
The on resistance profile of the ADG419 is very flat over the full
analog input range, ensuring excellent linearity and low distor-
tion. The part also exhibits high switching speed and high signal
bandwidth. CMOS construction ensures ultralow power dissipa-
tion, making the parts ideally suited for portable and battery
powered instruments.
2. Ultralow Power Dissipation
3. Low RON
4. Single Supply Operation
For applications where the analog signal is unipolar, the
ADG419 can be operated from a single rail power supply.
The part is fully specified with a single +12 V power supply
and will remain functional with single supplies as low as
+5 V.
Each switch of the ADG419 conducts equally well in both
directions when ON and has an input signal range that extends
to the supplies. In the OFF condition, signal levels up to the
supplies are blocked. The ADG419 exhibits break-before-
make switching action.
