Product details
Overview
ADUM3200TRZ-EP-RL7 from Analog Devices is a dual-channel, 25 Mbps digital isolator with reinforced 560 VPEAK insulation, 25 kV/µs common-mode transient immunity, and operation across −55°C to +125°C. It features two unidirectional input channels on the primary side (VIA/VIB), isolated outputs (VOA/VOB) on the secondary side, and supports 3.3 V or 5 V supplies on either side - enabling voltage translation in SPI isolation and battery monitor interfaces.
For engineers reviewing the ADUM3200TRZ-EP-RL7 datasheet, ADUM3200TRZ-EP-RL7 pinout, ADUM3200TRZ-EP-RL7 application, or ADUM3200TRZ-EP-RL7 equivalent, this enhanced product delivers military-grade ESD robustness per IEC 61000-4-x, high-temperature reliability, and narrow-body SOIC_N packaging for space-constrained industrial and aerospace systems.
Technical Context
The ADUM3200TRZ-EP-RL7 implements iCoupler® monolithic transformer isolation with CMOS interface circuitry on both sides, eliminating LED aging and timing drift inherent in optocouplers. Its dual-channel architecture provides galvanic separation between two independent digital signal paths without internal cross-talk.
It operates with asymmetric supply configurations (e.g., 5 V on VDD1 and 3.3 V on VDD2), maintains logic-level compatibility across the barrier, and includes built-in refresh circuitry ensuring output state retention during brief input-side power loss - critical for fault-tolerant serial bus interfaces.

Pinout & Package
Narrow-body, RoHS-compliant 8-lead SOIC_N (package option R-8), 5.00 mm × 4.00 mm footprint, 1.27 mm pitch, 1.75 mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD1 | Primary-side power supply | Provides 3.3 V or 5 V to input-side logic and isolation transmitter; decoupling required near pin. |
| 2 - VIA | Input A | Unidirectional digital input channel 1; accepts CMOS levels referenced to VDD1/GND1. |
| 3 - VIB | Input B | Unidirectional digital input channel 2; electrically isolated from VIA but shares same VDD1 domain. |
| 4 - GND1 | Primary-side ground | Reference return for VDD1, VIA, and VIB; must be separated from GND2 by ≥4 mm creepage/clearance. |
| 5 - GND2 | Secondary-side ground | Reference return for VDD2, VOA, and VOB; forms isolated domain boundary with GND1. |
| 6 - VOB | Output B | Unidirectional isolated output corresponding to VIB; driven by secondary-side logic powered by VDD2. |
| 7 - VOA | Output A | Unidirectional isolated output corresponding to VIA; compatible with 3.3 V or 5 V load logic. |
| 8 - VDD2 | Secondary-side power supply | Supplies isolated output-side circuitry; enables voltage translation when VDD2 ≠ VDD1. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM3201TRZ-EP-RL7 | 1 input/1 output per side (bidirectional configuration), identical package and specs otherwise. | Suitable for bidirectional protocols like I²C where channel direction must be dynamically controlled. | Select ADUM3201TRZ-EP-RL7 only if bidirectional signal flow is required; ADUM3200TRZ-EP-RL7 is optimal for fixed-direction SPI or control signaling. |
| SI8620ED-B-IS | Capacitive isolation, 25 Mbps, 5 kVrms rating, −40°C to +125°C (not extended military temp). | Lacks AQEC qualification and −55°C capability; lower CMTI (15 kV/µs). | Use SI8620ED-B-IS only in commercial/industrial applications where extended temperature and system-level ESD are not mandated. |
Compared with ADUM3201TRZ-EP-RL7 and SI8620ED-B-IS, the ADUM3200TRZ-EP-RL7 uniquely combines unidirectional dual-input architecture, −55°C operation, and IEC 61000-4-x hardened design - making it the sole choice for defense-grade SPI isolation where input-side signal density and extreme environmental resilience are mandatory.

FAQ
What is the maximum data rate supported by the ADUM3200TRZ-EP-RL7?
The ADUM3200TRZ-EP-RL7 supports a maximum data rate of 25 Mbps across its dual unidirectional channels. This specification is validated over the full −55°C to +125°C operating temperature range and applies under standard load conditions (CL = 15 pF). At lower rates (e.g., 1 Mbps), supply current drops to 1.7 mA per channel at 5 V, optimizing power efficiency for low-speed telemetry links.
Does the ADUM3200TRZ-EP-RL7 support mixed supply voltages?
Yes, the ADUM3200TRZ-EP-RL7 supports independent 3.3 V or 5 V supplies on each side - including mixed configurations such as VDD1 = 5 V and VDD2 = 3.3 V. This enables seamless voltage translation between legacy 5 V controllers and modern 3.3 V peripherals without external level-shifting components, while maintaining full 25 Mbps throughput and timing specifications.
What safety certifications apply to the ADUM3200TRZ-EP-RL7?
The ADUM3200TRZ-EP-RL7 carries pending approvals per UL 1577 (2500 Vrms, 1 minute), CSA Component Acceptance Notice 5A, and DIN V VDE V 0884-10 (VIORM = 560 VPEAK, reinforced insulation). The device is marked with an asterisk (*) indicating VDE certification and meets creepage/clearance requirements of ≥4.0 mm per safety standard.
How does the ADUM3200TRZ-EP-RL7 differ from the commercial ADUM3200 series?
The ADUM3200TRZ-EP-RL7 is the enhanced product (EP) variant featuring military-grade qualification: −55°C to +125°C operation, controlled manufacturing baseline, AQEC compliance, and enhanced system-level ESD robustness per IEC 61000-4-x. Unlike commercial versions, it undergoes extended reliability testing and provides full qualification data upon request - essential for defense and aerospace deployments.
What is the pin configuration of the ADUM3200TRZ-EP-RL7?
The ADUM3200TRZ-EP-RL7 uses an 8-lead narrow-body SOIC_N package (R-8) with pins: 1=VDD1, 2=VIA, 3=VIB, 4=GND1, 5=GND2, 6=VOB, 7=VOA, 8=VDD2. This configuration provides two input-only channels on Side 1 and two output-only channels on Side 2 - optimized for unidirectional protocols like SPI master-to-slave signaling.
