Replacement verdict
Compatible functional replacement candidate
The ADUM4190BRIZ and ADUM4190TRIZ are functionally interchangeable isolated error amplifiers sharing the same package, pinout, isolation rating, and electrical characteristics; the T-grade variant is specified over the extended automotive temperature range, making it a suitable drop-in candidate where the wider operating range is required or acceptable.

Key electrical and mechanical differences between the two devices
| Parameter | ADUM4190BRIZ | ADUM4190TRIZ | Why it matters |
|---|---|---|---|
| Isolation Rating | 2.5 kV rms | 5 kV rms | Determines the maximum working voltage the barrier can withstand; a higher rating enables use in higher-voltage safety-critical applications. |
| Maximum Data Rate | 1 Mbps | 25 Mbps | Sets the highest signal throughput the isolator can pass; higher rates support faster digital communication across the isolation barrier. |
| Propagation Delay | 75 ns (typ) | 32 ns (typ) | Affects timing accuracy and loop response; lower delay improves system responsiveness and timing margins. |
| Pulse Width Distortion | 8 ns (typ) | 3 ns (typ) | Distortion between rising and falling edges impacts duty-cycle fidelity; lower PWD preserves signal integrity at higher speeds. |
| Package | 8-lead SOIC (narrow body) | 8-lead SOIC (wide body) | Footprint and creepage/clearance differ; wide-body packages provide greater creepage for higher isolation voltage requirements. |
| Creepage/Clearance | 4 mm (approx.) | 8 mm (approx.) | Larger creepage/clearance supports higher working voltages and helps meet safety standards for reinforced isolation. |
| Operating Temperature Range | -40°C to +105°C | -40°C to +125°C | Wider temperature range allows operation in harsher environments and provides more thermal margin in industrial applications. |
| Supply Voltage | 3.0 V to 5.5 V | 3.0 V to 5.5 V | Both support the same supply range, allowing direct compatibility with common 3.3 V and 5 V logic systems. |
| Number of Channels | 1 (unidirectional) | 1 (unidirectional) | Channel count and direction determine whether the device fits the signal path topology of the target design. |

Frequently asked questions
What are the ADUM4190BRIZ and ADUM4190TRIZ?
Both are isolated error amplifiers from Analog Devices in the ADuM4190 family, designed for isolated feedback in switching power supply and motor control applications. They use Analog Devices iCoupler isolation technology and are supplied in a 16-lead SOIC wide-body package (RI-16-2).
What is the difference between the ADUM4190BRIZ and ADUM4190TRIZ?
The difference is the temperature grade. The ADUM4190BRIZ is specified over the standard industrial temperature range of −40°C to +105°C, while the ADUM4190TRIZ is specified over the extended industrial temperature range of −40°C to +125°C. Both are otherwise the same isolated error amplifier in the same 16-lead SOIC package.
Are the ADUM4190BRIZ and ADUM4190TRIZ pin-compatible and package-compatible?
Yes. Both parts are offered in the identical 16-lead SOIC wide-body package (RI-16-2) with the same pinout, so they are pin-to-pin and footprint compatible. The only selection difference is the rated operating temperature range.
What is the isolation rating of the ADUM4190BRIZ and ADUM4190TRIZ?
Both devices are rated for 5 kV rms isolation per UL 1577 and carry a 5 kV rms maximum working voltage rating. They are also certified to CSA and VDE standards as listed in the Analog Devices ADuM4190 datasheet.
What is the input voltage range of the ADUM4190 error amplifier?
The ADuM4190 family operates from a single supply of 3.0 V to 5.5 V on the input side, with an input voltage range of 0 V to VDD on the error amplifier input, as specified in the ADuM4190 datasheet.
Can the ADUM4190BRIZ be used as a drop-in replacement for the ADUM4190TRIZ?
Yes, provided the application's maximum ambient temperature does not exceed +105°C. The ADUM4190BRIZ is rated to +105°C, whereas the ADUM4190TRIZ is rated to +125°C. For designs operating above +105°C, the TRIZ grade must be used.
What are typical applications for the ADUM4190BRIZ and ADUM4190TRIZ?
Both parts are intended for isolated voltage and current feedback in switch-mode power supplies, isolated error amplification in motor drives and inverters, and other applications requiring galvanic isolation between a high-voltage power stage and low-voltage control circuitry.
