Product details
Overview
ADuM5212CRSZ from Analog Devices is a dual-channel digital isolator with integrated isoPower® DC-to-DC converter, delivering regulated 3.3 V or 5.0 V isolated output up to 150 mW, supporting data rates up to 100 Mbps (NRZ), and featuring 25 kV/µs common-mode transient immunity. It serves as a complete galvanic isolation solution for SPI interfaces, sensor signal conditioning, and gate drive biasing in industrial PLCs and RS-232 transceivers.
For engineers reviewing the ADuM5212CRSZ datasheet, ADuM5212CRSZ pinout, ADuM5212CRSZ application, or ADuM5212CRSZ equivalent, this page provides verified technical context, exact pin functions, confirmed operating parameters across 3.3 V/5 V configurations, safety-certified insulation specs (VIORM = 600 V peak, VISO = 2500 V rms), and real-world alternative selection guidance.
Technical Context
The ADuM5212CRSZ implements iCoupler® chip-scale transformer technology for both signal isolation and power transfer, eliminating external isolated DC-DC converters. Its dual-channel architecture supports independent input/output supply domains (VDD1/VDD2) and a dedicated primary power rail (VDDP) feeding the isoPower converter, with VSEL programmability enabling 3.3 V or 5.0 V isolated output.
It features soft-start power sequencing, thermal shutdown at 154°C, and reinforced insulation per DIN EN IEC 60747-17 (VDE 0884-17). The device operates across −40°C to +105°C and meets UL 1577, IEC/CSA 62368-1, and CQC GB 4943.1 safety standards with 5.3 mm creepage and clearance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel isolated power + signal applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADuM5211CRSZ | Channel direction reversed: VIA→VOA, VIB→VOB (input-output mapping swapped vs. ADuM5212CRSZ). | Requires PCB layout revision if signal routing assumes ADuM5212CRSZ's pinout; identical power specs and isolation ratings. | Select ADuM5211CRSZ only when matching existing board design with inverted channel assignment. |
| Si8822ED-IS | Capacitive isolation; 5 V output only; 100 Mbps data rate; lower max isolated power (120 mW). | Lacks VSEL programmability; requires external regulator for 3.3 V loads; higher EMI susceptibility than iCoupler magnetic coupling. | Choose Si8822ED-IS when 5 V-only operation suffices and capacitive isolation meets system EMC targets. |
Compared with ADuM5212CRSZ, ADuM5211CRSZ offers identical performance but inverted channel mapping-requiring layout changes-while Si8822ED-IS trades programmable output voltage and magnetic noise immunity for lower cost and different isolation physics, limiting flexibility in mixed-voltage systems.

FAQ
What is the maximum isolated output power of the ADuM5212CRSZ?
The ADuM5212CRSZ delivers up to 150 mW of isolated output power when configured for 5 V input and 5 V output. At 5 V input/3.3 V output, it provides 150 mW; at 3.3 V input/3.3 V output, maximum output is 66 mW. Power capability depends on input voltage, output voltage, and ambient temperature - full derating curves are specified in the ADuM5212CRSZ datasheet Section "Thermal Analysis".
Can the ADuM5212CRSZ operate with different input and output supply voltages?
Yes, the ADuM5212CRSZ supports independent supply domains: VDD1 (3.135–5.5 V) powers side-1 logic, VDD2 (3.135–5.5 V) powers side-2 logic, and VDDP (3.135–5.5 V) feeds the isoPower converter. VISO output is programmable to 3.3 V or 5.0 V regardless of VDD1/VDD2 values, enabling mixed-voltage system interfacing - e.g., 3.3 V MCU side-1 to 5 V actuator side-2.
How is the isolated output voltage (VISO) set on the ADuM5212CRSZ?
VISO is set using an external resistor divider between VISO and GNDISO connected to the VSEL pin, which compares against an internal 1.25 V reference. For 3.3 V output, R1 = 10 kΩ and R2 = 16.9 kΩ; for 5.0 V output, R1 = 10 kΩ and R2 = 30.9 kΩ. The ADuM5212CRSZ datasheet Table 2 and Figure 12 provide full design equations and layout guidelines for stable regulation.
Does the ADuM5212CRSZ require external components for basic operation?
Yes - the ADuM5212CRSZ requires external bypass capacitors (0.1 µF || 10 µF on VDDP and VISO), a VSEL resistor network for output voltage programming, and recommended ferrite beads and RC snubbers on VDDP per AN-0971 to meet CISPR 22 Class B emissions. No external transformers or inductors are needed, as the isoPower converter uses integrated chip-scale magnetics.
What safety certifications apply to the ADuM5212CRSZ?
The ADuM5212CRSZ is certified to UL 1577 (2500 V rms, 1 min), DIN EN IEC 60747-17 (VDE 0884-17, VIORM = 600 V peak), IEC/CSA 62368-1, IEC/CSA 61010-1, and CQC GB 4943.1. These approvals cover reinforced insulation for functional safety in industrial equipment, with 5.3 mm creepage/clearance and CTI >600 V - all verified per the official Analog Devices certification reports.
