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.
2. Low RON of 6.5 Ω.
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.
5. 3 V logic compatible digital inputs: VINH = 2.0 V, VINL = 0.8 V.
6. No VL logic power supply required.
7. Available in 8-lead MSOP package and 8-lead, 2 mm ×
3 mm LFCSP packages.
