ADG5423 GENERAL DESCRIPTION PRODUCT HIGHLIGHTS The ADG5421/ADG5423 are monolithic industrial, 1. Trench isolation guards against latch-up. A dielectric trench complementary metal oxide semiconductor (CMOS) analog separates the P channel and N channel transistors, thereby switches containing two independent latch-up immune single- preventing latch-up even under severe overvoltage pole/single-throw (SPST) switches. Each switch conducts equally conditions. well in both directions when on, and has an input signal range 2. Low RON of 13.5 . that extends to the power supplies. In the off condition, signal 3. Dual-supply operation. For applications where the analog levels up to the supplies are blocked. Both ADG5421 switches signal is bipolar, the ADG5421/ADG5423 can operate are turned on with a Logic 1 input, whereas the ADG5423 has from dual supplies up to 22 V. one switch turned on and one switch turned off for a Logic 1 4. Single-supply operation. For applications where the analog input. The ADG5423 exhibits break-before-make action for use signal is unipolar, the ADG5421/ADG5423 can operate from in multiplexer applications. a single-rail power supply up to 40 V. 5. 3 V logic compatible digital inputs: VINH = 2.0 V, VINL = 0.8 V. The ultralow on resistance and on-resistance flatness of these 6. No VL logic power supply required. switches make them ideal solutions for data acquisition and gain 7. Available in 10-lead MSOP and 10-lead 3 mm 3 mm switching applications where low distortion is critical. The LFCSP packages. latch-up immune construction and high ESD rating make these switches more robust in harsh environments. Rev.
