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.","metaTitle":"ADUM3190ARQZ iCoupler Isolated Error Amplifier, 16-QSOP","metaDescription":"ADUM3190ARQZ isolated error amplifier from ADI iCoupler series.
