**ADG5236BRUZ: A Comprehensive Technical Overview of the High-Voltage Latch-Up Immune Dual SPDT Switch**
The **ADG5236BRUZ** from Analog Devices represents a significant advancement in the design of high-performance analog switches, engineered to meet the stringent demands of modern industrial, instrumentation, and communication systems. This device is a **high-voltage, latch-up immune, dual single-pole/double-throw (SPDT)** switch that integrates robust protection with exceptional signal fidelity.
Constructed on an advanced **iCMOS® (industrial CMOS)** process, the ADG5236BRUZ is capable of handling bipolar analog signals with a wide supply range from **±5 V to ±22 V** or a single supply from **8 V to 44 V**. This flexibility makes it suitable for a vast array of applications, including **programmable logic controllers (PLCs), data acquisition systems, and automated test equipment (ATE)**, where it routes high-level analog signals with precision.
A defining characteristic of this switch is its **superior latch-up immunity**. Traditional CMOS devices are susceptible to latch-up, a destructive parasitic SCR effect triggered by voltage spikes or currents beyond absolute maximum ratings. The ADG5236BRUZ is specifically designed to be **immune to latch-up**, ensuring unparalleled reliability and system robustness in electrically noisy environments. This feature is critical for maintaining uptime in industrial settings where transient overvoltage events are common.
The device boasts low on-resistance (**R_ON**) of typically 60 Ω, which remains exceptionally flat across the entire analog signal range. This minimizes distortion and ensures accurate signal transmission, which is vital for high-precision measurement systems. Furthermore, it features **break-before-make switching action**, preventing momentary shorting between channels during switching transitions and protecting downstream circuitry.
Each switch conducts equally well in both directions when on and blocks signals effectively when off. The **leakage currents are exceptionally low** (sub-nanoamp levels), which is paramount for maintaining signal integrity in high-impedance circuits. The TTL/CMOS-compatible logic inputs simplify interface with modern controllers and FPGAs.
Housed in a compact **24-lead TSSOP package**, the ADG5236BRUZ offers a high level of integration in a small footprint, making it an excellent choice for space-constrained PCB designs. Its extended industrial temperature range (**-40°C to +125°C**) guarantees performance in harsh operating conditions.
**ICGOODFIND**: The ADG5236BRUZ stands out as a premier solution for system designers who prioritize **robustness, high-voltage operation, and signal integrity**. Its unique combination of latch-up immunity, wide voltage range, and low on-resistance makes it an indispensable component for creating reliable and high-performance systems in challenging environments.
