ADUM4195-1BRIZ

Overview

The ADUM4195-1BRIZ is an isolated amplifier based on iCoupler technology, featuring a fixed gain of 1 and single-ended output. It operates within a voltage supply range of 4.5 V to 5.5 V on both sides. The device provides galvanic isolation up to 5000 V rms for one minute according to UL 1577 standards. Key electrical characteristics include a bandwidth of 210 kHz, low offset error of ±5 mV at 25°C, and low gain drift of ±42 ppm/°C. It supports an ambient operating temperature range from -40°C to +125°C.

Feature Summary

• High-impedance input suitable for isolated voltage measurement applications
• Stable transfer function over lifetime and wide temperature range compared to optocouplers
• Certified for reinforced insulation with high common-mode transient immunity
• AEC-Q100 qualified for automotive applications

Applications

• Inverters
• DC-DC converters
• On-board chargers

Procurement Notes

Verify the specific suffix BRIZ indicates tube packaging containing 80 units per tube as listed in the ordering guide. Confirm RoHS compliance status associated with the Z suffix. Ensure the application environment does not exceed the maximum junction temperature of 150°C or the safety limiting power dissipation of 1.5 W under DIN EN IEC 60747-17 conditions.

Selection Notes

Select this component when a unity-gain isolated amplifier is required for high-voltage sensing. The fixed gain simplifies design by eliminating external resistor networks for gain setting. Consider the 210 kHz bandwidth and 3.5 µs output delay for dynamic signal requirements. Verify that the 5000 V rms isolation rating meets the safety standards of the target system, such as IEC 62368-1 or IEC 61010-1.

Part Context

This part belongs to the ADuM4195 family of isolation amplifiers utilizing Analog Devices' iCoupler technology. Unlike traditional optocouplers, it offers stable performance without current transfer ratio degradation. The BRIZ variant specifically denotes the standard commercial grade packaged in an 8-lead SOIC with increased creepage distance, distinct from the automotive-qualified W variants.
