GENERAL DESCRIPTION PRODUCT HIGHLIGHTS
The ADG5433 and ADG5434 are monolithic industrial CMOS 1. Trench isolation guards against latch-up. A dielectric trench analog switches comprising three independently selectable separates the P and N channel transistors thereby preventing single-pole, double-throw (SPDT) switches and four indepen- latch-up even under severe overvoltage conditions. dently selectable SPDT switches, respectively. 2. Low RON. All channels exhibit break-before-make switching action that 3. Dual-supply operation. For applications where the analog prevents momentary shorting when switching channels. An EN signal is bipolar, the ADG5433/ADG5434 can be operated input on the ADG5433 (LFCSP and TSSOP packages) is used to from dual supplies up to ±22 V. enable or disable the device. When disabled, all channels are 4. Single-supply operation. For applications where the analog switched off. signal is unipolar, the ADG5433/ADG5434 can be operated from a single-rail power supply up to 40 V. The ultralow on resistance and on-resistance flatness of these 5. 3 V logic compatible digital inputs: VINH = 2.0 V, VINL = 0.8 V. switches make them ideal solutions for data acquisition and gain 6. No VL logic power supply required. switching applications, where low distortion is critical.
