LC2MOS Precision Quad SPST Switches ADG431/ADG432/ADG433 FEATURES 44 V Supply Maximum Ratings V Analog Signal Range Low On Resistance <24 Ultralow Power Dissipation Low Leakage nA Fast Switching Times tON <165 ns tOFF <130 ns Break-Before-Make Switching Action TTL/CMOS Compatible Plug-in Replacement for DG411/DG412/DG413 APPLICATIONS Audio and Video Switching Automatic Test Equipment Precision Data Acquisition Battery Powered Systems Sample Hold Systems Communication Systems GENERAL DESCRIPTION The ADG431, ADG432 and ADG433 are monolithic CMOS devices comprising four independently selectable switches. They are designed on an enhanced 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 excellent linearity and low distortion when switching audio signals. Fast switching speed coupled with high signal bandwidth also make the parts suitable for video signal switching. CMOS construction ensures ultralow power dissipation making the parts ideally suited for portable and battery powered instruments. The ADG431, ADG432 and ADG433 contain four independent SPST switches. The ADG431 and ADG432 differ only in that the digital control logic is inverted. The ADG431 switches are turned on with a logic low on the appropriate control input, while a logic high is required for the ADG432. The ADG433 has two switches with digital control logic similar to that of the ADG431 while the logic is inverted on the other two switches. Each switch conducts equally well in both directions when ON and has an input signal range which extends to the 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.

Single Supply Operation For applications where the analog signal is unipolar, the ADG431, ADG432, and ADG433 can be operated from a single rail power supply.
