It combines an error amplifier with an isolation channel in a single 16-QSOP package, eliminating the need for an optocoupler and a separate reference or shunt regulator in the secondary-side sense path. Target applications include shunt regulators, linear power supplies, inverters, and UPS systems — any topology where the control loop must cross an isolation boundary while maintaining accuracy and stability. ## Package and mounting — narrow SSOP footprint It is a surface-mount part, intended for reflow assembly. The narrow-body footprint saves board area compared to wider SOIC alternatives, but the 0.154-inch (3.90 mm) width means the pad pattern must be verified against the QSOP land geometry — not a generic SOIC-16 footprint.","metaTitle":"ADUM3190BRQZ Isolator, Error Amplifier, iCoupler, 16-QSOP","metaDescription":"ADI ADUM3190BRQZ isolated error amplifier in 16-QSOP.
