Product details

Isolated error amplifier for feedback loops

The ADUM3190ARQZ from Analog Devices is an isolated error amplifier in the iCoupler® series, combining an error amplifier with galvanic isolation on a single die. It is designed for feedback control loops in isolated power converters, where it replaces optocoupler-based circuits with a more stable, higher-bandwidth solution. Typical applications include shunt regulators, linear power supplies, inverters, and UPS systems.

Package and footprint

The narrow-body SSOP footprint is common for isolated interface and amplifier ICs, and the QSOP variant is pin-compatible with standard SSOP-16 land patterns.

Lifecycle and compliance

It is ROHS3 compliant, meeting current European Union restriction-of-hazardous-substances requirements.

Frequently asked questions

What are the alternatives to ADUM3190ARQZ?

Within the iCoupler family, the ADUM3190 is the base isolated error amplifier. Higher isolation-rated variants (e.g., ADUM3190W) exist for automotive applications, but the ARQZ suffix specifies the 16-QSOP package and standard temperature range. No pin-compatible second source from another manufacturer is documented in the iCoupler portfolio.
