GENERAL DESCRIPTION

The ADG5401 is a monolithic industrial, complementary metal

oxide semiconductor (CMOS) analog switch containing a latch-

up immune single-pole/single-throw (SPST) switch. The 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.

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.

PRODUCT HIGHLIGHTS

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.

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

signal is bipolar, the ADG5401 can operate from dual

supplies of up to ±22 V.

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

signal is unipolar, the ADG5401 can operate from a single-

rail power supply of up to 40 V.

7. Available in 8-lead MSOP package and 8-lead, 2 mm ×

3 mm LFCSP packages.
