PRODUCT HIGHLIGHTS
1. Extended Signal Range
The ADG417 is fabricated on an enhanced LC
2
MOS process,
giving an increased signal range that extends to the supply
rails.
2. Ultralow Power Dissipation
3. Low R
ON
4. Single Supply Operation
For applications where the analog signal is unipolar, the
ADG417 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.
GENERAL DESCRIPTION
The ADG417 is a monolithic CMOS SPST switch. This switch
is designed on an enhanced LC
2
MOS process that provides low
power dissipation yet gives high switching speed, low on resis-
tance and low leakage currents.
The on resistance profile of the ADG417 is very flat over the
full analog input range ensuring excellent linearity and low
distortion. The part also exhibits high switching speed and high
signal bandwidth. CMOS construction ensures ultralow power
dissipation making the parts ideally suited for portable and
battery powered instruments.
The ADG417 switch, which is turned ON with a logic low on
the control input, 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 ADG417 exhibits break-before-make switching
action for use in multiplexer applications. Inherent in the design
is low charge injection for minimum transients when switching
the digital input.
