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 that 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 inject

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 RON.
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.
