Product details
Overview
ADUM3200TRZ-EP from Analog Devices is a dual-channel, reinforced digital isolator based on iCoupler® transformer technology, designed for high-reliability isolation in harsh environments. It supports 25 Mbps data rate, operates across −55°C to +125°C, delivers 25 kV/µs common-mode transient immunity, and features 560 VPEAK working voltage per VDE V 0884-10. It is used in SPI/data converter isolation and hybrid electric vehicle battery monitors.
For engineers reviewing the ADUM3200TRZ-EP datasheet, ADUM3200TRZ-EP pinout, ADUM3200TRZ-EP application, or ADUM3200TRZ-EP equivalent, key selection criteria include its military-grade temperature range, narrow-body SOIC-8 package, dual unidirectional channel configuration (2 inputs on VDD1 side, 0 on VDD2), and compliance with UL 1577 (2500 Vrms) and VDE V 0884-10 (reinforced insulation).
Technical Context
The ADUM3200TRZ-EP implements two independent unidirectional isolation channels using monolithic air-core transformers and integrated CMOS interface circuitry. Its architecture enables true galvanic signal transfer without optocoupler degradation or timing drift, supporting asymmetric supply operation (3.3 V/5 V or 5 V/3.3 V) across the barrier.
It features enhanced system-level ESD robustness per IEC 61000-4-x, controlled manufacturing baseline for defense/aerospace use, and safety-certified reinforced insulation (VIORM = 560 VPEAK). Pinout and truth table confirm fixed input-side channel assignment: VIA/VIB on Side 1, VOA/VOB on Side 2 - no cross-channel feedback or bidirectional logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 25 Mbps maximum - supports high-speed SPI clocking and real-time sensor data isolation without oversampling or protocol adaptation. |
| Operating Temperature | −55°C to +125°C - qualified for extended military and automotive under-hood applications without derating. |
| Common-Mode Transient Immunity | >25 kV/µs - maintains signal integrity in noisy motor drive or battery monitoring systems with fast-switching power stages. |
| Isolation Rating | 2500 Vrms for 1 minute (UL), 560 VPEAK working voltage (VDE) - meets reinforced insulation requirements for functional safety-critical subsystems. |
| Supply Voltage Range | 3.0 V to 5.5 V per side - enables direct interfacing with both 3.3 V microcontrollers and 5 V legacy peripherals across the barrier. |
| Propagation Delay | 20 ns to 45 ns (typ/max at 5 V) - ensures deterministic timing for closed-loop control signals and synchronized ADC sampling. |

Pinout & Package
Narrow-body, RoHS-compliant 8-lead SOIC_N (package option R-8), JEDEC MS-012-AA compliant, 5.00 mm × 4.00 mm body, 1.27 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD1 | Input-side supply rail | Provides power to input-side encoder and input buffers; must be decoupled locally to suppress switching noise coupling into isolation barrier. |
| 2 - VIA | Channel A input | Digital logic input referenced to GND1; accepts 3.3 V or 5 V CMOS levels; no internal pull-up/down. |
| 3 - VIB | Channel B input | Independent digital logic input on Side 1; identical electrical specs to VIA; supports parallel data path isolation. |
| 4 - GND1 | Input-side ground reference | Return path for VDD1 and input signals; must be isolated from GND2 by ≥4.0 mm creepage/clearance on PCB. |
| 5 - GND2 | Output-side ground reference | Return path for VDD2 and output drivers; forms secondary ground domain; no DC continuity to GND1. |
| 6 - VOB | Channel B output | CMOS-compatible output referenced to GND2; drives 3.3 V or 5 V logic loads up to ±22 mA per pin. |
| 7 - VOA | Channel A output | Independent output on Side 2; matches VOB timing and drive strength; supports synchronous dual-channel protocols. |
| 8 - VDD2 | Output-side supply rail | Power for output-side decoder and drivers; enables voltage translation (e.g., 3.3 V MCU → 5 V DAC interface). |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced insulation certification | VDE V 0884-10 (VIORM = 560 VPEAK) and UL 1577 (2500 Vrms) - eliminates need for external safety capacitors or creepage extenders in medical/industrial designs. |
| Military-grade environmental qualification | −55°C to +125°C operation with AQEC-aligned manufacturing baseline - ensures long-term reliability in defense avionics and space-qualified subsystems. |
| Enhanced system-level ESD performance | IEC 61000-4-x compliant design - reduces board-level filtering requirements and improves field failure resistance in industrial I/O modules. |
| Low-power high-speed operation | 1.7 mA/channel @ 1 Mbps (5 V) and 4.1 mA/channel @ 10 Mbps - extends battery life in portable test equipment and enables dense multi-isolator layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM3201TRZ-EP | Bidirectional channel configuration (1 input/1 output per side) vs. ADUM3200TRZ-EP's 2-input/0-output on Side 1. | Suitable for half-duplex UART or I²C isolation where direction control is required; not drop-in for SPI master-side isolation. | Select ADUM3201TRZ-EP only when bidirectional signal flow across the barrier is needed; pinout differs (VIA/VOA swapped on Side 1). |
| SI8620ED-IS | Capacitive isolation architecture; 25 Mbps rating; 5000 Vrms UL rating; VIORM = 600 VPEAK; different pinout and power sequencing requirements. | Approved for higher working voltages in industrial PLC backplanes; lacks AQEC-aligned manufacturing baseline for aerospace use. | Choose SI8620ED-IS for cost-sensitive industrial automation where extended temperature qualification is not required. |
Compared with ADUM3201TRZ-EP and SI8620ED-IS, the ADUM3200TRZ-EP uniquely combines military-grade temperature range, transformer-based noise immunity, and fixed 2-input unidirectional topology optimized for SPI master isolation - making it irreplaceable in defense-grade data acquisition and high-reliability EV battery monitoring.

FAQ
What is the channel configuration of the ADUM3200TRZ-EP?
The ADUM3200TRZ-EP has two unidirectional channels with both inputs (VIA and VIB) located on the VDD1 side and both outputs (VOA and VOB) on the VDD2 side. This 2-input/0-output configuration on Side 1 makes it ideal for isolating SPI master interfaces or parallel digital control signals without requiring direction control logic. The ADUM3200TRZ-EP truth table confirms fixed positive-logic behavior with no state-dependent output inversion.
Does the ADUM3200TRZ-EP support mixed-voltage operation?
Yes, the ADUM3200TRZ-EP supports asymmetric supply configurations: VDD1 and VDD2 may operate independently at either 3.3 V or 5 V. Valid combinations include 3.3 V/3.3 V, 5 V/5 V, 3.3 V/5 V, and 5 V/3.3 V. Electrical characteristics tables explicitly define performance for all four modes, including propagation delay (as low as 15 ns typ) and supply current, enabling seamless voltage translation in mixed-signal systems without level shifters.
What safety certifications apply to the ADUM3200TRZ-EP?
The ADUM3200TRZ-EP carries pending certifications for UL 1577 (2500 Vrms, 1 min), CSA Component Acceptance Notice 5A, and VDE V 0884-10 (reinforced insulation, VIORM = 560 VPEAK). It meets DIN V VDE V 0884-10:2006-12 requirements with 1050 VPEAK production test voltage and partial discharge detection <5 pC. The device bears an asterisk (*) marking on-package to indicate VDE approval.
How does the ADUM3200TRZ-EP differ from the commercial-grade ADUM3200ARZ?
The ADUM3200TRZ-EP is the enhanced product variant featuring military-grade temperature range (−55°C to +125°C), controlled manufacturing baseline, AQEC-aligned process controls, and enhanced system-level ESD reliability per IEC 61000-4-x. It uses the same R-8 SOIC package but includes product change notification and qualification data on request - unlike the commercial ADUM3200ARZ, which is rated only from −40°C to +105°C and lacks defense/aerospace qualification documentation.
What is the maximum recommended data rate for reliable operation of the ADUM3200TRZ-EP?
The ADUM3200TRZ-EP is specified for guaranteed operation up to 25 Mbps across its full temperature and supply voltage range. At this rate, propagation delay remains ≤45 ns (5 V), pulse width distortion ≤3 ns, and common-mode transient immunity exceeds 25 kV/µs. Operation beyond 25 Mbps is not characterized and may violate setup/hold timing margins or increase bit error rate due to PWD-induced jitter - the 25 Mbps limit is absolute per datasheet Table 1 and Ordering Guide.
