Product details
Overview
ADUM6424ABRNZ5 from Analog Devices is a quad-channel digital isolator with integrated isoPower® DC-to-DC converter, delivering 100 mA isolated output at 5 V or 3.3 V, supporting up to 100 Mbps signal isolation, and rated for automotive AEC-Q100 (Grade 1) operation up to 125°C. It eliminates external isolated power supplies in compact 500 mW isolated systems.
For engineers reviewing the ADUM6424ABRNZ5 datasheet, ADUM6424ABRNZ5 pinout, ADUM6424ABRNZ5 application, or ADUM6424ABRNZ5 equivalent, key selection factors include its 5.0 V primary / 3.3 V secondary supply configuration, 100 kV/µs common-mode transient immunity, CISPR 32 Class B compliance on 2-layer PCBs, and 28-lead SOIC package with 8.3 mm creepage.
Technical Context
The ADUM6424ABRNZ5 implements iCoupler® chip-scale transformer technology for both signal isolation and magnetic DC-DC conversion, enabling fully integrated galvanic isolation without external transformers or inductors. Its PWM-controlled flyback topology operates at 625 kHz with 180 MHz switching frequency, delivering regulated isolated output under load while maintaining low EMI.
It features four independent unidirectional isolation channels with asymmetric current consumption: low IDD1 (1.5–2.5 mA quiescent) on the primary side and high IDD2 (9.5–16 mA quiescent) on the isolated side - optimized for driving downstream isolated circuitry such as gate drivers or sensor interfaces.

Pinout & Package
ADUM6424ABRNZ5 uses a 28-lead, fine-pitch SOIC package (SOIC_W) with 1.27 mm pitch and 8.3 mm minimum creepage distance between primary and secondary sides. Pin assignments follow the standard ADuM642xA family layout with dedicated VDDP (primary power), VISO (isolated output), GNDP/GNDISO, and four channel pairs (A/B/C/D).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDP | Primary-side input supply | Accepts 4.5–5.5 V or 3.0–3.6 V; powers internal logic and DC-DC controller. |
| VISO | Isolated DC-DC output | Provides regulated 3.3 V or 5 V at up to 100 mA; powers isolated-side circuitry. |
| GNDP | Primary ground reference | Return path for VDDP; must be separated from GNDISO by ≥8.3 mm creepage. |
| GNDISO | Isolated ground reference | Return path for VISO and isolated-side outputs; forms galvanic barrier with GNDP. |
| INA, INB, INC, IND | Primary-side digital inputs | CMOS-compatible inputs referenced to VDDP/GNDP; drive corresponding isolated outputs. |
| OUTA, OUTB, OUTC, OUTD | Isolated-side digital outputs | CMOS outputs referenced to VISO/GNDISO; sink/source up to 3.2 mA per channel. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel isolated power applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM6424BRNZ5 | Higher propagation delay skew (tPSK = 10 ns vs. 8 ns) and reduced CMTI (75 kV/µs min) due to B-grade process binning. | Not AEC-Q100 qualified; suitable for industrial but not automotive use cases. | Select when cost sensitivity outweighs automotive qualification and ultra-low skew requirements. |
| SI88642ED-IS | Capacitive isolation architecture; 100 mA isolated supply at 5 V only; no 3.3 V VISO option; lower VIORM (425 V peak). | Lacks CISPR 32 Class B validation on 2-layer PCBs; requires additional EMI filtering for same emissions performance. | Choose for designs already committed to Silicon Labs' ecosystem and where 5 V-only isolated supply suffices. |
Compared with ADUM6424BRNZ5 and SI88642ED-IS, the ADUM6424ABRNZ5 uniquely combines AEC-Q100 qualification, dual-output voltage support (3.3 V/5 V), and guaranteed 100 kV/µs CMTI - making it the only option qualified for high-reliability automotive power electronics with tight timing constraints.

FAQ
What is the maximum isolated output current supported by ADUM6424ABRNZ5 at 3.3 V?
The ADUM6424ABRNZ5 delivers up to 100 mA at 3.3 V output under full-load conditions at 25°C. Current is derated linearly by 1.75 mA/°C above 85°C ambient, yielding 30 mA at 125°C. This specification is validated per Table 3 in the Rev. C datasheet and applies specifically to the ADUM6424ABRNZ5 variant with 5 V primary input.
Does ADUM6424ABRNZ5 support bidirectional data channels?
No, ADUM6424ABRNZ5 provides four unidirectional isolation channels (INA→OUTA, INB→OUTB, INC→OUTC, IND→OUTD). Directionality is fixed per channel; bidirectional operation requires external logic or separate transmit/receive isolators. This is confirmed in the Functional Block Diagram and Pin Configurations section of the datasheet.
What is the minimum creepage distance for ADUM6424ABRNZ5?
The ADUM6424ABRNZ5 package provides a minimum creepage distance of 8.3 mm between primary-side (pins 1–14) and secondary-side (pins 15–28) terminals, as specified in the Package Characteristics section (Table 17 footnote) and verified in the Outline Dimensions drawing.
Can ADUM6424ABRNZ5 operate with 1.8 V logic on the isolated side?
No - the ADUM6424ABRNZ5's isolated-side supply (VISO) is fixed at either 3.3 V or 5 V; it does not support 1.8 V output. While the isolated-side logic inputs/outputs are compatible with 1.8 V CMOS levels (per Table 16), the VISO pin must be supplied with 3.3 V or 5 V, and downstream 1.8 V circuitry requires an additional LDO.
Is ADUM6424ABRNZ5 pin-compatible with other ADuM642xA variants?
Yes - all ADuM642xA variants (including ADUM6420A through ADUM6424A) share identical 28-lead SOIC packaging and pinout. The ADUM6424ABRNZ5 differs only in channel direction assignment and quiescent current profile, not physical connectivity or footprint.
