LC2MOS精密四路SPST开关ADG431/adg432/adg433数据表

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 dissipa-tion making the parts ideally suited for portable and battery powered instruments.
The ADG431， ADG432 and ADG433 contain four indepen-dent 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.
