ADUM6028-3BRIZ

ADuM6028-3BRIZ is an 8‑channel digital isolator from Analog Devices (iCoupler technology). It provides galvanic isolation between two power/ground domains while transmitting digital signals across the isolation barrier, enabling safe interfacing of a microcontroller with noisy or high‑voltage circuitry.
Key points:
- Multi‑channel digital isolation for standard logic signals (e.g., SPI, I2C, UART, or generic GPIO).
- No optocouplers needed; compact, high‑reliability isolation suitable for industrial/automotive environments.
- Small package (BRIZ variant) designed for dense PCBs and rugged operation (industrial temperature range).
Typical uses:
- Isolating microcontrollers from motors, sensors, or external buses.
- Industrial automation, motor drives, medical devices, and energy meters.
Note:
For exact specs (propagation delay, data rate, isolation voltage, supply ranges, and the exact package), consult the ADI datasheet for ADuM6028-3BRIZ.

Here are some cross-references to ADuM6028-3BRI (8-ch, 5 kV, 5 V, high-speed digital isolator). You can parallel two 4-ch devices to get eight channels:
• Broadcom/Avago ACPL-784L/J
• TI ISO7721 / ISO7221
• Silicon Labs Si8621 / Si8641
• NVE IL715 / IL717
• ST STISO6B (6-ch) + STISO2 (2-ch)
• Infineon IL300 (2-ch; use four devices)

ADuM6028-3BRIZ features (concise):
- 3 independent digital isolation channels
- 5 kV RMS galvanic isolation between sides
- Dual-supply operation with VDD1 and VDD2; logic-compatible input/output on both sides
- High-speed data transfer per channel (typical Mbps range)
- Low propagation delay and low channel-to-channel skew
- High common-mode transient immunity
- Low static and dynamic power consumption
- Wide operating temperature (industrial range)
- 8-pin BRIZ package (compact, RoHS compliant)
Note: For exact electrical specs (voltage ranges, data rate, timing, and safety approvals), please consult the latest ADI datasheet.

ADUM6028-3BRIZ is supplied in a 16‑lead SOIC package (16 pins). It is an 8‑channel digital isolator (typically arranged as 4 channels in each direction). Key pin functions: VDD1 and GND1 (side‑1 power), VDD2 and GND2 (side‑2 power), and eight isolated logic I/O pins (the four side‑1→side‑2 channels and the four side‑2→side‑1 channels). Remaining pins are package‑specific NC/thermal or no‑connect pins per the datasheet.

Manufacturer: Analog Devices, Inc. (ADI).

Headquarters: Norwood, Massachusetts, USA.

ADuM6028-3BRIZ is a multi-channel digital isolator. Typical applications:
- Isolated I2C, SPI, and UART interfaces between microcontrollers/SoCs and peripherals
- Industrial automation and control systems (PLC, motor drives, sensors)
- Data acquisition and instrumentation requiring galvanic isolation
- Medical devices needing patient safety isolation
- Automotive electronics for isolated sensor/ECU communications
- Power electronics and renewable energy equipment
- Telecom/network gear to suppress ground loops and EMI
These use cases exploit galvanic isolation to improve safety, noise immunity, and reliability in diverse environments.

The ADuM6028-3BRIZ comes in a 16‑lead SOIC surface‑mount package (SOIC‑16, narrow). The “-3BRIZ” suffix indicates Pb‑free, tape‑and‑reel packaging and industrial temperature range.
