Product details
Overview
ADUM4190TRIZ-EP from Analog Devices is a reinforced-isolation, high-stability isolated error amplifier with 5000 Vrms isolation, 0.5% initial error accuracy, 1% total error over −55°C to +125°C, 400 kHz output −3 dB bandwidth, and integrated 1.225 V reference - designed for feedback control in linear power supplies and DOSA-compatible modules.
For engineers reviewing the ADUM4190TRIZ-EP datasheet, ADUM4190TRIZ-EP pinout, ADUM4190TRIZ-EP application, or ADUM4190TRIZ-EP equivalent, this page delivers verified specifications, military-grade thermal stability, dual isolated outputs (EAOUT/E AOUT2), Type II/III compensation compatibility, and safety-certified reinforced insulation per UL 1577, VDE V 0884-10, and CSA 5A.
Technical Context
The ADUM4190TRIZ-EP integrates a wideband op amp (10 MHz GBW, 80 dB open-loop gain) and precision 1.225 V reference on the secondary side, enabling direct comparison of output voltage against setpoint across the isolation barrier. Its dual-output architecture provides EAOUT (buffered, rail-to-rail capable) and EAOUT2 (open-drain, VDD1-referenced), supporting flexible loop compensation topologies.
Reinforced isolation is achieved via iCoupler® technology with 1013 Ω input-to-output resistance and 2.2 pF inter-side capacitance, delivering >100 kV/μs common-mode transient immunity. The device operates from 3.0 V to 20 V on both sides, with UVLO thresholds at 2.96 V (rising) and 2.6 V (falling), ensuring robust startup under brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 5000 Vrms reinforced - meets UL 1577, VDE V 0884-10, and CSA 5A for safety-critical power supply feedback loops |
| Reference Accuracy | 1.225 V ±10 mV (−55°C to +125°C) - enables precise output regulation without external trimming |
| Initial Error | 0.5% - ensures tight initial setpoint matching in closed-loop power systems |
| Output Bandwidth | 400 kHz typical (−3 dB) - supports fast transient response in high-density DC/DC converters |
| Supply Range | VDD1/VDD2 = 3.0 V to 20 V - compatible with 3.3 V, 5 V, 12 V, and 20 V bias rails on both sides |
| Op Amp Input Range | 0.35 V to 1.5 V - optimized for use with 1.225 V reference and standard resistor-divider feedback networks |
| Total Supply Current | <7 mA (IDD1 + IDD2) - minimizes auxiliary power draw in low-quiescent designs |
Pinout & Package
ADUM4190TRIZ-EP is housed in a wide-body 16-lead SOIC package (RI-16-2) with increased creepage (8.3 mm) and clearance (8.0 mm), compliant with JEDEC MS-013-AC and rated for reinforced 5000 Vrms isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, VDD2 | Primary and secondary supply inputs | Independent 3.0–20 V rails; each requires local 1 μF decoupling to respective GND |
| GND1, GND2 | Isolated ground references | Physically separated grounds maintain galvanic isolation; no shared return path |
| +IN, −IN | Op amp noninverting/inverting inputs | +IN accepts reference or setpoint; −IN connects to feedback divider and compensation network |
| COMP | Op amp output node | Drives external Type II/III compensation network between COMP and −IN |
| EAOUT | Primary isolated output | Buffered, rail-to-rail output (0.4–2.5 V) referenced to GND2; drives optocoupler replacement circuits |
| EAOUT2 | Secondary isolated output | Open-drain output referenced to VDD1; requires external pull-up for 0.3–5.4 V logic-level interface |
| REFOUT, REFOUT1 | 1.225 V reference outputs | Side 2 (REFOUT) and Side 1 (REFOUT1) provide matched, low-noise references for dual-sided sensing |
| NC (Pin 5) | No connection | Must be tied to GND1 - floating condition violates internal bias requirements |
Key Features
| Feature | Design Value |
|---|---|
| Stable transfer function over lifetime | Eliminates optocoupler CTR degradation - no recalibration needed across 15+ year deployments |
| Military temperature range support | Full specification guaranteed from −55°C to +125°C - qualified per AQEC for defense/aerospace use |
| Dual isolated outputs (EAOUT + EAOUT2) | Enables simultaneous analog feedback and digital fault signaling across isolation barrier |
| Type II/III compensation compatibility | Direct integration with standard power supply loop compensation networks - no external op amp required |
| Low 1.7 mVrms EAOUT noise | Preserves signal integrity in high-gain feedback paths - avoids false overvoltage/undervoltage trips |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated error amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM4190ARIZ | Commercial-grade version; same pinout and electrical specs but rated only for −40°C to +125°C and lacks AQEC qualification | Suitable for industrial, not defense/aerospace programs; no enhanced product change notification or controlled baseline | Select ADUM4190ARIZ only when military temp range and defense traceability are unnecessary |
| Si8920AC-ISR | Capacitive isolation; 3.75 kVrms rating; 1.23 V reference; 250 kHz bandwidth; higher supply current (10 mA) | Limited to commercial/mid-temp applications; lower isolation voltage restricts use in high-voltage UPS or aerospace systems | Choose Si8920AC-ISR where cost sensitivity outweighs need for 5 kVrms and extended temperature performance |
Compared with ADUM4190ARIZ, the ADUM4190TRIZ-EP adds −55°C operation, AQEC compliance, and production traceability - critical for flight hardware. Against Si8920AC-ISR, it delivers 33% higher bandwidth, 33% tighter reference accuracy, and 5000 Vrms reinforced isolation required for safety-critical power systems.

FAQ
What is the operating temperature range of the ADUM4190TRIZ-EP?
The ADUM4190TRIZ-EP is fully specified from −55°C to +125°C and qualified per AQEC standards for defense and aerospace applications. All key parameters - including 0.5% initial error, 1.225 V reference accuracy, and 400 kHz bandwidth - are guaranteed across this full range, with no derating required.
How does the ADUM4190TRIZ-EP differ from standard optocoupler-based feedback solutions?
Unlike optocouplers, the ADUM4190TRIZ-EP has no current transfer ratio (CTR) degradation over time or temperature. Its transfer function remains stable across its lifetime and over −55°C to +125°C, eliminating calibration drift and improving long-term power supply accuracy beyond what optocouplers can achieve.
Can the ADUM4190TRIZ-EP replace an optocoupler directly in an existing design?
The ADUM4190TRIZ-EP is not a drop-in optocoupler replacement due to its active architecture and dual-supply requirement. It requires redesign of the feedback network to use the integrated op amp and reference, but eliminates external components like shunt regulators and improves transient response and accuracy significantly.
What safety certifications does the ADUM4190TRIZ-EP hold?
The ADUM4190TRIZ-EP carries UL recognition (5000 Vrms, 1 min per UL 1577), CSA Component Acceptance Notice 5A, and VDE certificate of conformity to DIN V VDE V 0884-10:2006-12, with VIORM = 849 V peak and reinforced insulation classification.
What is the purpose of the EAOUT2 pin on the ADUM4190TRIZ-EP?
EAOUT2 is an open-drain output referenced to VDD1, providing a second isolated signal path for fault indication or auxiliary control. When used with an external pull-up resistor, it delivers logic-level signals (0.3–5.4 V) that can trigger shutdown or status reporting without loading the primary EAOUT feedback path.
