ADUM6411BRSZ

ADUM6411BRSZ is a four-channel digital isolator from Analog Devices (iCoupler family). It provides galvanic isolation between two power domains (VDD1 and VDD2) so signals can cross a barrier without a direct electrical connection.
Key points:
- Four digital channels with isolation for each path
- Uses iCoupler technology for transformerless, chip-scale isolation
- Bidirectional or unidirectional data paths across the barrier
- Separate supply rails on each side (VDD1 and VDD2)
- Fast edge rates and low propagation delay; low power consumption
- Typical isolation ratings around several kilovolts (per device family)
- RoHS-compliant packaging (BRSZ suffix)
Typical uses:
- Isolated data transfer between a microcontroller and peripherals
- Industrial controls, motor drives, power electronics, medical devices, and data acquisition systems requiring isolation
Note:
- For exact electrical specs (data rate, propagation delay, voltage ranges, and isolation rating), consult the ADuM6411 data sheet. The BRSZ suffix refers to the specific RoHS packaging variant.

ADuM6411BRSZ features (concise):
- 4-channel digital isolator (iCoupler) with IsoPower for isolated power transfer
- 5 kV RMS isolation between primary and secondary sides
- Data rate up to tens of Mbps per channel (typical performance in this family)
- Isolated power: no external regulator needed on the isolated side
- Compatible with 3.3 V and 5 V logic on both sides
- TTL/CMOS-level I/O with robust protection and low propagation delay
- Industrial temperature range: -40°C to +125°C
- 16‑lead RoHS-compliant package (RSZ)
- Low power consumption and fault/short-circuit tolerance features
- Suitable for MCU/Data-AC isolation, I/O isolation for sensors, motor drives, and medical/industrial applications
Notes: refer to the datasheet for exact figures (data rate per channel, propagation delay, supply voltage ranges) for precise design.

ADUM6411BRSZ comes in a 16‑lead plastic SOIC package (RoHS-compliant).

- Pin count: 16 pins (16‑lead package, e.g., SOIC/MSOP variant).
- Function: ADuM6411BRSZ is a 4‑channel digital isolator (iCoupler) that provides four isolated unidirectional data channels across an isolation barrier, enabling galvanic isolation between two systems for digital signal transfer.

Analog Devices, Inc. (ADI) is the manufacturer. It is a multinational American semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits (ICs), sensors, and related products.

Applications of ADUM6411BRSZ (quad-channel digital isolator):
- Isolated digital interfaces between MCU and high-voltage/noisy domains
- Isolated SPI, UART, I2C and general-purpose signals
- Industrial automation and process control
- Motor control and power electronics
- Automotive instrumentation and body electronics
- Medical devices and data acquisition systems
