Product details
Overview
ADuM4152ARIZ from Analog Devices is a 7-channel SPIsolator digital isolator with four high-speed SPI signal channels (CLK, MO/SI, MI/SO, SS) and three independent 250 kbps data channels, supporting up to 17 MHz SPI clock speed, 14 ns propagation delay on fast channels, and 5 kV rms isolation rating in a 20-lead SOIC_IC package rated for 125°C operation. It enables robust isolated communication between microcontrollers and isolated peripherals in industrial PLCs and sensor interfaces.
For engineers reviewing the ADuM4152ARIZ datasheet, ADuM4152ARIZ pinout, ADuM4152ARIZ application, or ADuM4152ARIZ equivalent, key selection criteria include its 17 MHz SPI clock support, 250 kbps auxiliary channel capability, reinforced insulation per VDE 0884-17, 645 V peak VIORM, and SOIC_IC package with 8.3 mm creepage - all critical for safety-certified industrial control designs.
Technical Context
The ADuM4152ARIZ implements iCoupler® chip-scale transformer technology to deliver galvanic isolation across a single 5 kV rms barrier. Its architecture separates four bidirectional SPI signals (MCLK, MSS, MO/SI, MI/SO) into high-speed channels with 14 ns typical propagation delay and <1 ns jitter, while three unidirectional low-speed channels (VIA, VIB, VIC → VOA, VOB, VOC) operate at 250 kbps with 2.5 µs jitter and asynchronous sampling.
It supports mixed-voltage operation (3.3 V/5 V or 5 V/3.3 V on either side), features glitch filtering on the MSS signal, and maintains >25 kV/µs common-mode transient immunity. The device includes undervoltage lockout (2.6 V) and meets reinforced insulation requirements per IEC 62368-1, IEC 60601-1, and DIN EN IEC 60747-17 (VDE 0884-17).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| SPI Clock Rate | Up to 17 MHz - enables full-speed SPI communication with microcontrollers and ADCs without timing bottlenecks. |
| High-Speed Propagation Delay | 14 ns typical - ensures tight timing alignment for MCLK, MO/SI, MI/SO, and MSS signals in real-time control loops. |
| Low-Speed Data Rate | 250 kbps - supports isolated status, configuration, or alarm signals over three independent channels. |
| Isolation Rating | 5000 V rms for 1 minute - certified for reinforced insulation in industrial and medical safety-critical systems. |

| Operating Temperature | −40°C to +125°C - suitable for extended-temperature industrial environments including motor drives and factory automation. |
| Common-Mode Transient Immunity | >25 kV/µs - prevents data corruption during fast-switching noise events in variable-frequency drives and power converters. |
Pinout & Package
ADuM4152ARIZ uses a 20-lead wide-body SOIC_IC package (package code: RW-20) with 8.3 mm creepage distance and reinforced insulation barrier separating side 1 (VDD1 domain) and side 2 (VDD2 domain). Pin 1 is marked with a dot; pins 1–10 form the input-side bank, pins 11–20 the output-side bank.

| GND1 | Side 1 ground | Reference for all side 1 inputs (MCLK, MSS, MO, SO, VIA, VIB, VIC). |
| MCLK | SPI master clock input | Drives isolated clock to slave side; supports up to 17 MHz with 14 ns delay. |
| MSS | SPI slave select input | Glitch-filtered signal ensuring reliable frame synchronization across isolation barrier. |
| MO/SI | Master-out/slave-in input | Transmits data from master MCU to isolated peripheral; high-speed channel. |

| VDD2 | Side 2 supply | 3.0–5.5 V power for output-side logic and isolation receiver circuitry. |
| GND2 | Side 2 ground | Reference for all side 2 outputs (SCLK, SSS, MI, SI, VOA, VOB, VOC). |
| SCLK | Isolated SPI clock output | Reconstructed MCLK on side 2; matches input timing within 1 ns jitter. |
| SSS | Isolated slave select output | Glitch-filtered replica of MSS, synchronized to SCLK for deterministic slave enable. |
| MI/SI | Master-in/slave-out output | Receives SO/MI data on side 2; used for peripheral-to-MCU return path. |
| SI/MO | Slave-in/master-out output | Drives MO/SI data to peripheral; completes full-duplex SPI link across isolation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADuM4151ARIZ | Same 7-channel architecture but with different channel direction assignment: MSS is output-only on side 2; lacks glitch filter on MSS. | Less suitable for master-initiated slave-select arbitration where glitch immunity is critical. | Select ADuM4152ARIZ when MSS must be reliably filtered and driven from side 1 to side 2 with deterministic timing. |
| ISO7741FQDWR | TI 4-channel digital isolator with 100 Mbps data rate per channel; no native SPI optimization or auxiliary slow channels. | Requires external logic to reconstruct SPI framing and separate control signals; higher layout complexity. | Choose ADuM4152ARIZ when integrated SPI signal mapping, timing matching, and three extra 250 kbps channels reduce system-level design effort. |
Compared with ADuM4151ARIZ, ADuM4152ARIZ adds MSS glitch filtering and optimized channel direction for master-driven SPI topologies; versus ISO7741FQDWR, it delivers purpose-built SPI timing, integrated auxiliary channels, and reinforced safety certification - reducing component count and validation effort in industrial and medical designs.

FAQ
What is the maximum SPI clock frequency supported by the ADuM4152ARIZ?
The ADuM4152ARIZ supports up to 17 MHz SPI clock frequency when operating at 5 V on both sides. At 3.3 V supply, the maximum clock rate is 12.5 MHz; with mixed 5 V/3.3 V operation, it achieves 15.6 MHz. These values are validated across −40°C to +125°C and reflect guaranteed timing margins for reliable data capture in real-time systems using the ADuM4152ARIZ.
Does the ADuM4152ARIZ support mixed-voltage operation between its two sides?
Yes, the ADuM4152ARIZ supports mixed-voltage operation: VDD1 can be 3.3 V while VDD2 is 5 V, or vice versa. Electrical specifications - including propagation delay, data rate, and output drive strength - are fully characterized for both configurations in the official datasheet. This flexibility allows seamless interfacing between legacy 5 V peripherals and modern 3.3 V microcontrollers using the ADuM4152ARIZ.
How many isolation channels does the ADuM4152ARIZ provide, and what are their functions?
The ADuM4152ARIZ provides seven galvanically isolated channels: four high-speed SPI signal channels (MCLK, MSS, MO/SI, MI/SO) and three independent 250 kbps data channels (VIA→VOA, VIB→VOB, VIC→VOC). All channels reside within a single 20-lead SOIC_IC package and share the same 5 kV rms isolation barrier - a core architectural advantage of the ADuM4152ARIZ.
What safety certifications apply to the ADuM4152ARIZ?
The ADuM4152ARIZ is certified to UL 1577 (5000 V rms, 1 min), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (1 MOPP), IEC/CSA 61010-1, and DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation. Its VIORM is 645 V peak, and it meets creepage/clearance requirements of 8.3 mm - all verified and documented for the ADuM4152ARIZ in its official regulatory summary.
Can the ADuM4152ARIZ be used in medical equipment requiring IEC 60601-1 compliance?
Yes, the ADuM4152ARIZ is explicitly certified for IEC 60601-1 compliance as a reinforced insulation component with 1 MOPP (Means of Patient Protection). Its 645 V peak VIORM, 5000 V rms isolation rating, and VDE 0884-17 approval make it suitable for isolated data acquisition, sensor interfaces, and digital control paths in Class I and Class II medical devices - confirmed in the ADuM4152ARIZ safety documentation.
