GENERAL DESCRIPTION

The ADG451/ADG452/ADG453 are monolithic CMOS

devices comprising four independently selectable switches.

They are designed on an enhanced LC

MOS process that

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, makes 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 ADG451/ADG452/ADG453 contain four independent,

single-pole/single-throw (SPST) switches. The ADG451 and

ADG452 differ only in that the digital control logic is inverted. The

ADG451 switches are turned on with a logic low on the appropriate

control input, while a logic high is required for the ADG452.

Figure 3. ADG453

The ADG453 has two switches with digital control logic similar

to that of the ADG451, while the logic is inverted on the other

two switches.

Each switch conducts equally well in both directions when on,

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 ADG453 exhibits 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.

ADG451/ADG452/ADG453 PRODUCT HIGHLIGHTS 1. Low RON (5 Ω maximum). 2. Ultralow Power Dissipation. 3. Extended Signal Range. The ADG451/ADG452/ADG453 are fabricated on an enhanced LC2MOS process, giving an increased signal range that fully extends to the supply rails. 4. Break-Before-Make Switching. This prevents channel shorting when the switches are configured as a multiplexer (ADG453 only.) 5. Single-Supply Operation.

ADG451/ADG452/ADG453 APPLICATIONS Figure 15 illustrates a precise, fast, sample-and-hold circuit. An AD845 is used as the input buffer, and the output operational amplifier is an AD711. During track mode, SW1 is closed, and the output, VOUT, follows the input signal, VIN. In hold mode, SW1 is opened, and the signal is held by the hold capacitor, CH.
