SWITCHES SHOWN FOR A LOGIC “1” INPUT
GENERAL DESCRIPTION
The ADG333A is a monolithic CMOS device comprising four
independently selectable SPDT switches. It is designed on an
LC²MOS process which provides low power dissipation yet
achieves a high switching speed and a low on resistance.
The on resistance profile is very flat over the full analog input
range ensuring good linearity and low distortion when switching
audio signals. High switching speed also makes the part suitable
for video signal switching. CMOS construction ensures ultralow
power dissipation making the part ideally suited for portable,
battery powered instruments.
When they are ON, each switch conducts equally well in both
directions and has an input signal range which extends to the
power supplies. In the OFF condition, signal levels up to the
supplies are blocked. All switches exhibit 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 inputs.
PRODUCT HIGHLIGHTS
1. Extended Signal Range
The ADG333A is fabricated on an enhanced LC²MOS
process, giving an increased signal range which extends
to the supply rails.
2. Low Power Dissipation
3. Low R_ON
4. Single Supply Operation
For applications where the analog signal is unipolar,
the ADG333A can be operated from a single rail power
supply. The part is fully specified with a single +12 V
supply.
