GENERAL DESCRIPTION
The ADG436 is a monolithic CMOS device comprising two
independently selectable SPDT switches. It is designed on an
LC²MOS process, which provides low power dissipation yet
gives high switching speed and 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 and battery-powered instruments.
Each switch conducts equally well in both directions when on
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 ADG436 is fabricated on an enhanced LC²MOS
process, giving an increased signal range that 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
ADG436 can be operated from a single rail power supply.
