523 0 The on resistance profile is very flat over the full analog input Figure 3. ADG453 range, ensuring excellent linearity and low distortion when The ADG453 has two switches with digital control logic similar switching audio signals. Fast switching speed, coupled with high to that of the ADG451, while the logic is inverted on the other signal bandwidth, makes the parts suitable for video signal two switches. switching. CMOS construction ensures ultralow power dissipa- tion, making the parts ideally suited for portable and battery- Each switch conducts equally well in both directions when on, powered instruments. and each has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. The ADG451/ADG452/ADG453 contain four independent, single-pole/single-throw (SPST) switches. The ADG451 and The ADG453 exhibits break-before-make switching action for ADG452 differ only in that the digital control logic is inverted. The use in multiplexer applications. Inherent in the design is low ADG451 switches are turned on with a logic low on the appropriate charge injection for minimum transients when switching the control input, while a logic high is required for the ADG452. digital inputs.
