GENERAL DESCRIPTION
The ADG5419 is a monolithic industrial, complementary metal
oxide semiconductor (CMOS) analog switch containing a latch-
up immune single-pole/double-throw (SPDT) switch.
Each switch conducts equally well in both directions when on,
and each switch has an input signal range that extends to the
power supplies. In the off condition, signal levels up to the
supplies are blocked. The ADG5419 exhibits break-before-make
switching action for use in multiplexer applications.
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 13.5 Ω.
3. Dual-supply operation. For applications where the analog
signal is bipolar, the ADG5419 can be operated from dual
supplies up to ±22 V.
4. Single-supply operation. For applications where the analog
signal is unipolar, the ADG5419 can be operated from a
single-rail power supply 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 and 8-lead, 2 mm × 3 mm
LFCSP packages.
