ADUM3196ARWZ - Isolated Error Amplifier | Analog Devices
MPN： ADUM3196ARWZ ✓ 啟用中ADUM3196ARWZ 概覽
An isolated error amplifier is a specialized component that amplifies the difference between a reference voltage and a feedback signal while providing galvanic isolation between the input and output. This isolation is critical in power supplies where the primary and secondary sides must be electrically separated for safety and noise immunity. The ADUM3196ARWZ integrates this function into a single SOIC-16 package, reducing board space and component count compared to discrete solutions.
Key features of the ADUM3196ARWZ include a 400 kHz bandwidth, a typical offset voltage of 0.5 mV, and a gain of 1 V/V. The device provides reinforced isolation with a working voltage of 1000 Vrms and a transient immunity of 25 kV/us, ensuring reliable operation in harsh industrial environments. It also features an internal 1.0V reference, simplifying the design of feedback networks.
The ADUM3196ARWZ uses Analog Devices' iCoupler technology, which integrates magnetic isolation with analog circuitry on a single chip. This architecture provides precise signal transfer across the isolation barrier without the need for external optocouplers or separate isolation amplifiers. The device is designed for high reliability, with a typical isolation lifetime of 50 years at 1000 Vrms working voltage.
Typical applications include isolated DC-DC converters, AC-DC power supplies, and isolated voltage sensing in industrial, automotive, and telecommunications systems. The device is particularly suited for applications requiring high accuracy and stability over temperature, such as server power supplies and battery chargers.
When designing with the ADUM3196ARWZ, ensure proper PCB layout to maintain isolation spacing and minimize parasitic capacitance. The device requires a bypass capacitor on both supply pins, and the feedback network should be placed close to the error amplifier inputs to reduce noise pickup.

設計說明
For the ADUM3196ARWZ, maintain proper isolation spacing between primary and secondary sides on the PCB. Use a minimum creepage distance of 8 mm for reinforced isolation per IPC-2221. Place bypass capacitors (0.1 uF) close to VDD1 and VDD2 pins to ensure stable operation.
Keep the feedback network components (resistors and capacitors) close to the IN+ and IN- pins to minimize parasitic capacitance and noise pickup. Use a ground plane on the primary side, but avoid routing high-voltage traces under the device to prevent coupling.
Do not exceed the absolute maximum supply voltage of 20V on either side. Ensure that the input voltage does not exceed the supply voltage to prevent latch-up. Also, verify that the output load does not exceed the device's drive capability, which is typically 1 mA.
