GENERAL DESCRIPTION

The ADG5421/ADG5423 are monolithic industrial,

PRODUCT HIGHLIGHTS

complementary metal oxide semiconductor (CMOS) analog

switches containing two independent latch-up immune single-

pole/single-throw (SPST) switches. Each switch conducts

equally well in both directions when on, and has an input signal

range that extends to the power supplies. In the off condition,

signal levels up to the supplies are blocked. Both ADG5421

switches are turned on with a Logic 1 input, whereas the

ADG5423 has one switch turned on and one switch turned off

for a Logic 1 input. The ADG5423 exhibits break-before-make

action for use in multiplexer applications.

1. Trench isolation guards against latch-up. A dielectric trench

separates the P channel and N channel transistors, thereby

preventing latch-up even under severe overvoltage

conditions.

2. Low R_ONof 13.5 Ω.

3. Dual-supply operation. For applications where the analog

signal is bipolar, the ADG5421/ADG5423 can operate

from dual supplies up to 22 V.

4. Single-supply operation. For applications where the analog

signal is unipolar, the ADG5421/ADG5423 can operate from

a single-rail power supply up to 40 V.

5. 3 V logic compatible digital inputs: V_INH= 2.0 V, V_INL= 0.8 V.

6. No V_Llogic power supply required.

7. Available in 10-lead MSOP package.

The ultralow on resistance and on-resistance flatness of these

switches make them ideal solutions for data acquisition and gain

switching applications where low distortion is critical. The

latch-up immune construction and high ESD rating make these

switches more robust in harsh environments.
