ADUM4190TRIZ-EP-RL

Overview

The ADUM4190TRIZ-EP-RL is an enhanced product isolated error amplifier based on iCoupler technology, designed for linear feedback power supplies. It features a wide voltage supply range of 3.0 V to 20 V and operates within a military temperature range of −55°C to +125°C. The device provides stable performance with 0.5% initial error accuracy and 1% total error over the full temperature range. Key electrical parameters include a 10 MHz gain-bandwidth product, 72 dB common-mode rejection ratio, and a typical output bandwidth of 400 kHz. It incorporates a high-accuracy 1.225 V reference and supports reinforced isolation up to 5000 V rms.

Feature Summary

• Stable transfer function that does not change over lifetime or temperature, unlike optocoupler solutions.
• Integrated wideband operational amplifier supporting Type II or Type III compensation networks.
• High accuracy internal reference output voltage of 1.225 V for precise setpoint comparison.
• Enhanced product qualification supporting defense and aerospace applications under AQEC standards.

Applications

• Linear feedback power supplies
• Inverters
• Uninterruptible power supplies (UPS)
• DOSA-compatible modules
• Voltage monitors

Procurement Notes

Verify the specific suffix -EP-RL indicates the reel packaging variant of the Enhanced Product grade. Confirm that the component meets the required AQEC standard for defense and aerospace applications. Ensure the design accommodates the military temperature range specifications. Check for controlled manufacturing baseline requirements involving single assembly and fabrication sites as defined in the datasheet.

Selection Notes

Select this component when long-term stability and predictable current transfer ratios are critical, replacing traditional optocouplers. It is suitable for designs requiring fast transient response and high common-mode transient immunity. Consider the 16-lead SOIC package dimensions and the need for external compensation networks connected to the COMP pin. Verify compatibility with the target power supply loop architecture and voltage levels.

Part Context

This part belongs to the ADuM4190 series of isolated error amplifiers manufactured by Analog Devices. The -EP designation signifies Enhanced Product status, which includes controlled manufacturing baselines and qualification data availability. It utilizes iCoupler technology to provide galvanic isolation without the degradation issues associated with light-emitting diodes found in optical isolators.
