Analog Devices Inc. ADG5236BRUZ

Summary of the ADG5236BRUZ Device

The ADG5236BRUZ, manufactured by Analog Devices, is a high-performance, monolithic CMOS device that integrates two independently selectable single-pole/double-throw (SPDT) analog switches in a compact 16-lead TSSOP package. Designed to meet the rigorous demands of high-voltage signal routing, the ADG5236BRUZ's robust architecture and low on-resistance make it a compelling choice for a wide array of industrial and instrumentation applications, including precision data acquisition, analog front ends, and relay replacement scenarios. Its broad signal and supply voltage range, combined with latch-up immunity and minimal charge injection, cater to high-fidelity and high-reliability system requirements.

Main Attributes and Innovations of the ADG5236BRUZ

Central to the ADG5236BRUZ’s reliability is its trench isolation technology, which provides effective latch-up immunity by physically separating the P and N channel transistors with a dielectric trench. This innovation ensures dependable operation even under severe overvoltage or fault conditions, a critical advantage in complex signal environments. The ADG5236BRUZ features an off source capacitance as low as 2.5 pF and a maximum charge injection of just 0.6 pC, supporting fast settling and low-glitch performance ideal for sample-and-hold and data acquisition applications. Additionally, the device supports both dual (±9 V to ±22 V) and single (9 V to 40 V) supply operation, accommodating both unipolar and bipolar analog signals while maximizing design flexibility. Logic-compatible digital inputs (VINH ≥ 2.0 V, VINL ≤ 0.8 V) and break-before-make switching action further facilitate safe, interference-immune multiplexing.

Electrical Specifications and Switching Performance of the ADG5236BRUZ

The ADG5236BRUZ delivers consistently low on-resistance values—160 Ω typical under ±15 V dual supply and 150 Ω typical under 36 V single supply—minimizing signal distortion across its wide voltage range. Channel-to-channel on-resistance matching is tight, with typical values of 1.4 Ω, and flatness figures support linear performance across input ranges. Leakage currents are exceptionally low, with maximum source or drain off-leakage at 0.4 nA even at elevated temperatures, preventing signal degradation in sensitive analog paths. Dynamic performance is equally robust, with typical transition times as low as 150 ns and a 3 dB bandwidth up to 266 MHz, making the ADG5236BRUZ viable for both audio and high-speed video switching. Its off isolation and crosstalk performance, both at -85 dB @ 1 MHz for dual/36 V supply, ensure high channel-to-channel integrity in dense analog multiplexing environments.

Environmental Requirements and Packaging Choices for the ADG5236BRUZ

The ADG5236BRUZ is specified for reliable operation from -40°C to +125°C (ambient), making it suitable for industrial and automotive-grade designs. It operates with supply voltages up to ±22 V (dual) or up to 40 V (single-supply), and is robust against absolute maximum voltages up to 48 V on VDD to VSS. Continuous current ratings per channel range from 14 mA (TSSOP, 12 V supply, 25°C) up to 35 mA (LFCSP, 36 V supply). The primary package option for the ADG5236BRUZ is a space-efficient 16-lead TSSOP (4.40 mm width), with board-level thermal characteristics and RoHS3/REACH environmental compliance, supporting both surface-mount manufacturing and long-term reliability. No additional logic supply voltage (VL) is required, further simplifying implementation.

Design Guidelines and Usage Applications for the ADG5236BRUZ

The combination of latch-up immunity, flexible supply compatibility, and high off-isolation renders the ADG5236BRUZ highly attractive for application engineers designing automatic test equipment, precision acquisition circuits, industrial controls, and analog signal multiplexers. Its fast switch times and low charge injection suit time-critical paths such as sample-and-hold circuits and high-speed data routing. The device’s ability to block analog signals up to its full supply range in the off state ensures robustness for protection circuits and relay replacements. The break-before-make feature is essential for preventing shorting in multiplexer or signal routing systems. The ADG5236BRUZ’s low power consumption and compact footprint make it efficient in multi-channel systems where board space and thermal management are of concern. Attention should be given to ensure the package’s continuous current ratings align with system-level fault and load conditions.

Possible Alternative or Substitute Devices for the ADG5236BRUZ

When considering functionally similar analog switches as substitutes or drop-in replacements for the ADG5236BRUZ, engineers should focus on key parameters including channel count, on-resistance, voltage handling, leakage, and switching speed. Potential alternative options from Analog Devices or other vendors include the ADG733 or ADG1636 (with variations in channel count or voltage range), provided that their voltage, capacitance, and latch-up immunity features are compatible with application requirements. Careful attention must be paid to unavailable or reduced voltage ratings and to the physical package compatibility during substitution. Cross-comparison of off-leakage and dynamic performance is also necessary to preserve signal fidelity in demanding measurement or switching environments.
