Product details
Overview
ADUM6404CRIZ from Analog Devices is a quad-channel digital isolator with integrated isoPower® DC-to-DC converter, delivering up to 400 mW isolated output power at 5 V or 3.3 V, supporting 25 Mbps NRZ data rates, and providing 5 kV rms reinforced isolation in a 16-lead SOIC wide-body (RI-16-1) package for medical and industrial power supply gate drive applications.
For engineers reviewing the ADUM6404CRIZ datasheet, ADUM6404CRIZ pinout, ADUM6404CRIZ application, or ADUM6404CRIZ equivalent, this page delivers verified specifications, validated pin functions, confirmed safety certifications (UL, VDE, IEC 60601-1), and real-world design context for isolated RS-485 transceivers, AC/DC bias supplies, and sensor interfaces requiring integrated power and signal isolation.
Technical Context
The ADUM6404CRIZ implements iCoupler® transformer-based isolation across four independent channels with Schmitt-triggered inputs and bidirectional signal capability. Its isoPower core uses high-frequency switching (625 kHz PWM, 180 MHz oscillator) to transfer regulated 3.3 V or 5 V power across the isolation barrier without external magnetics.
It features undervoltage lockout (2.4 V–2.7 V thresholds) on all supplies, thermal shutdown at 150°C with 20°C hysteresis, and achieves >25 kV/μs common-mode transient immunity. The RI-16-1 package provides 8.3 mm creepage and 846 V peak reinforced insulation per DIN V VDE V 0884-10.

Applications
| Medical Isolation | AC/DC Power Supply Bias |
|---|---|
Use Scenario: Isolating patient-connected analog front-ends (ECG, EEG) from digital processing units in Class II medical equipment. IC Role / Device Role / Timing Role: Provides galvanic separation between low-voltage sensor domain and microcontroller domain while powering isolated ADC drivers via VISO. Use Value: Meets IEC 60601-1 250 V rms working voltage requirement with single-component reinforced insulation, eliminating dual-isolator architectures. |
Use Scenario: Delivering startup bias and gate drive power to primary-side controllers in offline flyback or LLC converters. IC Role / Device Role / Timing Role: Supplies isolated 5 V/3.3 V to UCC289x or similar controllers while transmitting PWM enable/fault signals across the barrier. Use Value: Replaces discrete transformer + LDO + optocoupler chain, reducing component count by ≥7 parts and improving startup reliability. |
| Isolated Sensor Interface | RS-485 Transceiver Isolation |
Use Scenario: Conditioning and isolating current/voltage measurements from shunt-based motor phase sensing in industrial inverters. IC Role / Device Role / Timing Role: Isolates analog-to-digital conversion signals and provides local 3.3 V power to isolated sigma-delta modulators (e.g., AD7403). Use Value: Enables direct connection to high-side shunts without level-shifting; 25 Mbps supports oversampled delta-sigma bitstreams. |
Use Scenario: Isolating half-duplex RS-485 transceivers (e.g., ADM3485) in factory automation networks exposed to ground potential differences. IC Role / Device Role / Timing Role: Separates transceiver logic pins (RO, DI, DE, RE) from MCU GPIOs while powering the transceiver's VCC_IO rail via VISO. Use Value: Prevents ground loop currents from corrupting differential bus signaling; >25 kV/μs CMTI suppresses noise from adjacent VFDs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel isolated power+signal applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM6404ARIZ | A-grade version: wider propagation delay range (55–100 ns vs. 45–65 ns), lower max data rate (1 Mbps vs. 25 Mbps) | Suitable only for low-speed control signaling (e.g., enable lines, status flags), not for high-speed feedback or serial comms | Select ADUM6404ARIZ only when timing budget allows ≥100 ns skew and data rate ≤1 Mbps. |
| SI88642ED-IS | Silicon Labs part: 5 kV isolation, 100 Mbps data rate, but no integrated DC-DC; requires external isolated power | Requires separate isolated DC/DC (e.g., ISOW7841), increasing board area and cost; higher speed suits Ethernet PHY isolation | Choose SI88642ED-IS when 100 Mbps is mandatory and external power is acceptable; avoid if BOM simplification is critical. |
Compared with ADUM6404ARIZ, the ADUM6404CRIZ enables faster closed-loop response in motor control; compared with SI88642ED-IS, it eliminates external power components but trades off maximum data rate-making ADUM6404CRIZ optimal for space-constrained 25 Mbps applications needing self-contained isolation.

FAQ
What is the maximum continuous output current supported by ADUM6404CRIZ at 5 V output?
The ADUM6404CRIZ delivers up to 80 mA continuous output current when configured for 5 V output from a 5 V input (IISO(MAX) = 80 mA), enabling direct powering of small isolated microcontrollers or transceivers without external regulators. This value is specified in Table 2 of the Rev. B datasheet under "Output Supply Current".
Does ADUM6404CRIZ support both 3.3 V and 5 V isolated output voltages?
Yes, ADUM6404CRIZ supports selectable isolated output voltages: tie VSEL to GNDISO for 3.3 V output, or to VISO for 5 V output. Output regulation is maintained across load ranges (e.g., 10–90 mA for 3.3 V @ 5 V input), with load regulation ≤5% as specified in Tables 6 and 10.
What safety certifications apply to ADUM6404CRIZ in the RI-16-1 package?
ADUM6404CRIZ in the RI-16-1 package holds UL recognition (5000 V rms, 1 min), VDE certification per DIN V VDE V 0884-10 (reinforced, 846 V peak), IEC 60601-1 (250 V rms), and IEC 60950-1 (400 V rms). These are documented in Table 15 and Regulatory Information section of the datasheet.
Can ADUM6404CRIZ be used in high-noise motor drive environments?
Yes, ADUM6404CRIZ is rated for >25 kV/μs common-mode transient immunity (|CM|), verified per test conditions in Table 5. This performance ensures reliable operation in inverter gate drive circuits where fast dV/dt edges induce large ground differentials across isolation barriers.
What is the thermal shutdown behavior of ADUM6404CRIZ?
ADUM6404CRIZ activates thermal shutdown at TJ = 150°C (TSSD) with 20°C hysteresis (TSSD-HYS), allowing automatic recovery once junction temperature falls below 130°C. This protects against sustained overloads and inadequate PCB copper, as defined in Table 14 and Figure 7 of the datasheet.
