Analog Devices Inc. ADG5213BRUZ

Product Summary ADG5213BRUZ by Analog Devices Inc.

The ADG5213BRUZ, manufactured by Analog Devices Inc., is a robust, high-voltage quad single-pole/single-throw (SPST) analog switch supplied in a compact 16-lead TSSOP package. Designed to serve the needs of engineers working in environments demanding high reliability and precision, the ADG5213BRUZ is ideally suited for data acquisition, instrumentation, automatic test equipment, avionics, audio/video routing, and advanced communication systems.

Main Functions of the ADG5213BRUZ

The ADG5213BRUZ brings multiple best-in-class attributes:

High-voltage operation supporting ±9 V to ±22 V dual-supply or 9 V to 40 V single-supply configurations, with a maximum limit of 48 V.

Four totally independent switches per device, each capable of passing signals equally well in both directions, with input signal range extending up to the supply rails.

Ultrahigh immunity to latch-up thanks to proprietary trench isolation technology, safeguarding against device failure in overvoltage scenarios.

Exceptionally low parasitic attributes: only 3 pF off source capacitance, 5 pF off drain capacitance, and ≤0.07 pC charge injection, crucial for minimizing glitches and achieving fast, clean settling in precision analog circuits.

Sub-nanoampere off-state leakage (0.2 nA at +85°C) to support high-accuracy measurements and limit signal degradation.

Digital input compatibility with standard 3 V logic thresholds across the entire supply range, eliminating the need for a dedicated logic power rail.

Technical Overview and Architecture Trench Isolation with Digital Control

Central to the ADG5213BRUZ’s robustness is the use of Analog Devices’ trench isolation, a sophisticated dielectric barrier placed between NMOS and PMOS transistor wells in each CMOS switch. This structure eliminates the parasitic junctions that in classical junction-isolated switches can form silicon-controlled rectifiers (SCRs) and thereby cause latch-up under overstress or a fault condition.

By physically and electrically isolating PMOS and NMOS elements, trench isolation in the ADG5213BRUZ guarantees that even under severe transient or overvoltage conditions, device integrity is preserved, making it suitable for mission-critical and safety-demanding systems.

Regarding control logic, the ADG5213BRUZ features two switches with standard logic and two with inverted logic for flexible design. The absence of a separate VL logic supply pin streamlines board layout, and the device supports direct interfacing with 3 V logic levels, a major benefit when integrating with modern microcontrollers or digital systems.

Electrical Specifications and Reliability Data for ADG5213BRUZ

The ADG5213BRUZ is fully specified at common industry voltages: ±15 V, ±20 V, +12 V, and +36 V. At these levels, on-resistance (RON) is consistently low (typically 160 Ω), and stays flat across the switch’s full analog signal range. This is essential for predictable, flat signal transmission paths.

Leakage currents, both channel off and on, remain at minimized levels (typically ≤0.2 nA), supporting precise signal integrity and reducing error margins in sensitive analog circuitry. The switch can handle continuous currents per channel (as per Absolute Maximum Ratings) in demanding applications without degradation.

Designed to withstand up to 48 V supply transients, the ADG5213BRUZ further integrates enhanced electrostatic discharge (ESD) protections to help safeguard sensitive downstream circuitry in development and production environments. Engineers should note, however, that standard handling for ESD-sensitive components always applies.

Performance Metrics Capacitance, Charge Injection, Leakage Current, and On-Resistance

From a signal performance standpoint, the ADG5213BRUZ is optimized for minimal signal loss and distortion:

Low off source (3 pF) and drain (5 pF) capacitances reduce crosstalk, preserve bandwidth, and facilitate high-speed analog signal processing.

The charge injection specification of only 0.07 pC ensures that digital switching introduces negligible glitch energy—extremely important in precision sample-and-hold and high-speed data acquisition systems.

Flat and predictable on-resistance across varying input signals and temperatures, with detailed RON vs. signal and thermal characteristics provided to guide signal path design.

Off isolation and crosstalk are carefully characterized across frequency to assist engineers designing for high-speed or high-fidelity analog routing.

Fast switching times and low tON/tOFF values minimize propagation delay and ensure signal timing is predictable in time-critical applications.

Use Cases for the ADG5213BRUZ

The ruggedness and performance profile of the ADG5213BRUZ make it a compelling choice for:

Automatic test equipment (ATE), where high voltage tolerance, low leakage, and glitch-free switching are essential for repeated precision testing cycles.

Data acquisition systems and instrumentation—especially for high-precision ADC and DAC front-ends requiring minimal charge injection and low leakage.

Avionics and aerospace electronics, which benefit from the switch’s latch-up immunity and wide supply voltage acceptance.

Audio and video routing, where fidelity is dictated by low capacitance, quick switching, and consistent resistance flatness.

Communications infrastructure, especially in analog signal routing or protection applications exposed to overvoltage and high transient noise.

Package Variants and Pin Configuration Details of ADG5213BRUZ

The ADG5213BRUZ is delivered in a JEDEC-compliant, 16-lead TSSOP (Thin Shrink Small Outline Package) with concise dimensions that ease dense multidimensional board layouts. The exposed pad is tied to the substrate (VSS), supporting optimal grounding for noise performance. Pin function documentation and logic truth tables support fast schematic integration and correct system-level control assignment.

Possible Alternatives/Replacement Options for ADG5213BRUZ

Product selection engineers evaluating alternatives to the ADG5213BRUZ should consider related devices from Analog Devices Inc.’s own catalog such as the ADG5212 series, which shares much of the same core high voltage latch-up-proof technology but with variations in control logic and configuration. Key distinctions between these models often center on switch logic polarity, presence or absence of break-before-make functionality, and pin-to-function mapping.

It is advisable to compare datasheet parameters closely for specific attributes such as RON, leakage, voltage range, and packaging, as subtle differences may be significant depending on end-application constraints. For cross-brand alternatives, attention must also be paid to the presence of trench or similar isolation technology to ensure equivalent latch-up protection.
