GENERAL DESCRIPTION

The ADG5412/ADG5413 contain four independent single-

pole/single-throw (SPST) switches. The ADG5412 switches

turn on with Logic 1. The ADG5413 has two switches with

digital control logic similar to that of the ADG5412; however,

the logic is inverted on the other two switches. Each switch

conducts equally well in both directions when on, and each

switch has an input signal range that extends to the supplies.

In the off condition, signal levels up to the supplies are blocked.

inputs are compatible with 3 V logic inputs over the full

operating supply range.

The on-resistance profile is very flat over the full analog input

range, which ensures good linearity and low distortion when

switching audio signals. High switching speed also makes the

devices suitable for video signal switching. The ADG5413

exhibits break-before-make switching action for use in

multiplexer applications.

PRODUCT HIGHLIGHTS

1.

Trench isolation guards against latch-up. A dielectric trench

separates the P and N channel transistors thereby preventing

latch-up even under severe overvoltage conditions.

2.

3.

Dual-supply operation. For applications where the analog

signal is bipolar, the ADG5412/ADG5413 can be operated

from dual supplies up to ±22 V.

4.

Single-supply operation. For applications where the analog

signal is unipolar, the ADG5412/ADG5413 can be operated

from a single rail power supply up to 40 V.
