Analog Devices Inc. ADUM4153ARIZ-RL

Overview

ADuM4153ARIZ-RL 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 for industrial PLC and sensor isolation applications.

For engineers reviewing the ADuM4153ARIZ-RL datasheet, ADuM4153ARIZ-RL pinout, ADuM4153ARIZ-RL application, or ADuM4153ARIZ-RL equivalent, this page delivers verified timing parameters, regulatory compliance details (UL 1577, VDE 0884-17), SOIC_IC package mapping, and real-world isolation channel configuration guidance for SPI bus design.

Technical Context

The ADuM4153ARIZ-RL implements iCoupler® chip-scale transformer technology to achieve low-jitter, low-propagation-delay isolation across both high-speed and low-speed channels. Its four fast channels support bidirectional SPI timing-critical signals with 14 ns typical tPHL/tPLH and ≤1 ns jitter, while three slow channels use asynchronous sampling at 250 kbps with 2.5 µs jitter.

It operates across mixed-supply configurations (3.3 V/5 V, 5 V/3.3 V, or same-rail), maintains >25 kV/µs common-mode transient immunity, and enforces reinforced insulation per DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 645 V peak and 8.3 mm creepage in the 20-lead SOIC_IC package.

Key Specifications

FAQ

What is the maximum SPI clock rate supported by the ADuM4153ARIZ-RL?

The ADuM4153ARIZ-RL supports up to 17 MHz SPI clock rate under 5 V operation, with 14 ns typical propagation delay and ≤1 ns jitter on high-speed channels (MCLK, MO/SI, MI/SO, MSS). At 3.3 V operation, the maximum clock rate is 12.5 MHz, and mixed-supply configurations (e.g., 5 V/3.3 V) support up to 15.6 MHz. These values are specified in Tables 1 and 4 of the Rev. D datasheet.

Does the ADuM4153ARIZ-RL support mixed-voltage operation between primary and secondary sides?

Yes, the ADuM4153ARIZ-RL supports mixed-voltage operation: VDD1 and VDD2 may be independently set to 3.0–5.5 V, including combinations such as 5 V on VDD1 and 3.3 V on VDD2 (Table 7) or 3.3 V on VDD1 and 5 V on VDD2 (Table 10). This eliminates external level shifters in heterogeneous voltage domain systems.

How many isolation channels does the ADuM4153ARIZ-RL provide, and what are their data rates?

The ADuM4153ARIZ-RL provides seven total isolation channels: four high-speed SPI signal channels (MCLK, MSS, MO/SI, MI/SO) operating up to 34 Mbps, and three low-speed auxiliary channels (VIA/VIB/VIC → VOA/VOB/VOC) operating at 250 kbps. All channels maintain galvanic isolation with 5 kV rms rating and >25 kV/µs CMTI.

What safety certifications apply to the ADuM4153ARIZ-RL?

The ADuM4153ARIZ-RL is certified to UL 1577 (5000 V rms, 1 minute), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (1 MOPP, 544 V rms), IEC/CSA 61010-1, and DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 645 V peak. These are documented in Tables 14 and 15 of the Rev. D datasheet.

What is the package type and creepage distance of the ADuM4153ARIZ-RL?

The ADuM4153ARIZ-RL uses a 20-lead SOIC_IC (wide-body SOIC_W) package with 8.3 mm minimum creepage and clearance distances, as confirmed in the Package Characteristics section (Table 13) and Outline Dimensions (Page 20) of the Rev. D datasheet. This meets reinforced insulation requirements for pollution degree 2.
