ADG5236BRUZ-RL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG5236BRUZ-RL7 is a monolithic CMOS device containing two independently selectable single-pole/double throw (SPDT) switches. It operates from ±9 V to ±22 V dual supplies or 9 V to 40 V single supplies, with maximum ratings of 48 V. The device features trench isolation for latch-up immunity and ultralow capacitance (2.5 pF source off, 12 pF drain off). On-resistance ranges from 160 Ω to 350 Ω depending on supply voltage. Switching times are typically 170 ns (tON) and 160 ns (tOFF) at ±15 V. It includes break-before-make switching action and low charge injection of −0.6 pC.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Trench isolation technology prevents latch-up under all circumstances, including severe overvoltage conditions.
• Ultralow off-source and off-drain capacitance combined with minimal charge injection ensures fast settling and low glitch performance.
• Supports both dual-supply operation up to ±22 V and single-supply operation up to 40 V.
• Features 3 V logic-compatible digital inputs without requiring a separate VL logic power supply.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the reel packaging configuration when sourcing components. Confirm that the BRUZ variant matches the required TSSOP-16 package dimensions and thermal characteristics for your PCB layout. Ensure compatibility with the specified -40°C to +125°C operating temperature range for your application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring high voltage handling and robust latch-up protection in harsh environments. Consider the on-resistance flatness and leakage current specifications relative to your signal integrity requirements. Verify that the 3 V logic interface aligns with your control system's output levels without additional level shifting circuitry.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG5236 belongs to Analog Devices' ADG52xx family of high-voltage, latch-up proof switches. This family is designed for instrumentation, industrial, automotive, and aerospace applications prone to latch-up issues. The BRUZ designation indicates the 16-lead Thin Shrink Small Outline Package (TSSOP) variant within this series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the same family include the ADG5236BRUZ without the RL7 suffix for tape-and-reel variations. Other models in the ADG52xx series may offer different channel counts or configurations but share similar latch-up proof technologies.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ADG5236 achieve latch-up immunity?

It uses a dielectric trench isolation layer between the P and N channel transistors, eliminating parasitic junctions that could form silicon controlled rectifiers (SCRs) during overvoltage conditions.

What is the break-before-make time delay?

The break-before-make time delay (tD) ensures that one switch opens before the other closes, preventing short circuits in multiplexer applications. It is typically 75 ns at ±15 V dual supply.

Can the ADG5236 handle bipolar signals?

Yes, the analog signal range extends from VSS to VDD, allowing it to handle bipolar signals when operated from dual supplies ranging from ±9 V to ±22 V.
