GENERAL DESCRIPTION

The ADG411, ADG412, and ADG413 are monolithic CMOS

devices comprising four independently selectable switches.

They are designed on an enhanced LC

MOS 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 ADG411, ADG412, and ADG413 contain four independent

SPST switches. The ADG411 and ADG412 differ only in that

the digital control logic is inverted. The ADG411 switches are

turned on with a logic low on the appropriate control input,

while a logic high is required for the ADG412. The ADG413

has two switches with digital control logic similar to that of the

ADG411 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.

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 ADG411, ADG412, and ADG413 are fabricated on an

enhanced LC

MOS, giving an increased signal range which

extends fully to the supply rails.

2. Ultralow power dissipation

3. Low R

4. Break-before-make switching

This prevents channel shorting when the switches are

configured as a multiplexer.

5. Single-supply operation

For applications where the analog signal is unipolar, the

ADG411, ADG412, and ADG413 can be operated from a

single-rail power supply. The parts are fully specified with a

single 12 V power supply and remain functional with single

supplies as low as 5 V.

ADG411/ADG412/ADG413 APPLICATIONS Due to switch and capacitor leakage, the voltage on the hold capacitor decreases with time. The ADG411/ADG412/ADG413 minimizes this droop due to its low leakage specifications. The droop rate is further minimized by the use of a polystyrene hold capacitor. The droop rate for the circuit shown is typically 30 μV/μs. the hold time glitch while optimizing the acquisition time.
