ADUM3400CRWZ-RL Übersicht
A digital isolator is an integrated component that transmits binary data across an electrical isolation barrier using non-conducting coupling mechanisms, replacing legacy optocouplers in modern industrial and instrumentation designs. Digital isolators sit hierarchically between general-purpose isolators and the broader signal conditioning and interface IC family, and they are commonly deployed upstream of an MCU's GPIO, downstream of a sensor's logic output, or across the high-side/low-side boundary in motor-drive and power-converter systems. Where applicable, they replace optocouplers with the benefits of higher speed, tighter channel matching, and lower timing skew.
Key features of the ADUM3400CRWZ-RL include a 90 Mbps guaranteed signaling rate per channel (5 V operation), a CMTI rating of 25 kV/us minimum, and enhanced system-level ESD reliability per IEC 61000-4-x. The device operates from 2.7 V to 5.5 V on either side of the barrier, supports 4/0 channel directionality (all four channels the same direction), and consumes a low 1.4 mA per channel at 0 Mbps to 2 Mbps. The package provides a withstand-to-works rating of 2500 Vrms for 1 minute per UL 1577 and is rated for 5 kV HBM ESD on the I/O pins.
The iCoupler architecture combines high-speed CMOS with monolithic air-core transformers, achieving data rates roughly 5-10x faster than optocouplers at a fraction of the LED-degradation-related concerns. The 16-SOIC wide-body footprint gives 8 mm of minimum external clearance, and the device is qualified for industrial temperature ranges.
Typical uses include isolated SPI/UART interfaces between microcontrollers and high-voltage drivers, gate-drive signal isolation in motor-control inverters, isolated data acquisition between ADCs and FPGAs, and industrial fieldbus (RS-485, CAN) interface isolation. The wide temperature range also supports harsh industrial environments.
When designing with this part, observe the 8 mm minimum external clearance required by the wide-body SOIC footprint for 2500 Vrms reinforced isolation. The two supply pins (VDD1 and VDD2) must be bypassed with 0.1 uF capacitors placed as close as possible to the IC. Pin 4 (DISABLE input) and the four data channels follow a specific logic convention that must be respected during power-up sequencing.

Typische Anwendungen
ADUM3400CRWZ-RL ist geeignet für 6 Anwendungs: Isolated SPI Bus Interface, Isolated UART Interface, Industrial Fieldbus (Modbus / CAN) Interface, Isolated Gate Drive Signal Path, Isolated ADC Data Acquisition, Isolated Sensor Signal Conditioning.
Isolated SPI Bus Interface
The ADUM3400CRWZ-RL fits isolated SPI bus interfaces between microcontrollers and peripheral ICs because its 90 Mbps data rate exceeds the typical 10-50 Mbps SPI requirement, with 2500Vrms withstand per UL 1577 protecting low-voltage logic from upstream faults. Per the ADI datasheet, all four channels share the same direction so clock/MOSI/CS lines travel one way while MISO returns on a separate isolator. The 25 kV/us CMTI rating suppresses dv/dt transients common in motor drive ground references, and the wide-body 16-SOIC gives 8 mm creepage required for reinforced isolation in IEC 60730 white goods.

Isolated UART Interface
For isolated UART interfaces, the ADUM3400CRWZ-RL delivers the 921 kbps launch, with 2500Vrms withstand and 25 kV/us CMTI isolating the bus in the 4/0 direction for TX path. Per the ADI datasheet, the wide-body 16-SOIC footprint satisfies IEC 60730 reinforced isolation in industrial controllers and HVAC equipment. Compared to an optocoupler, the iCoupler architecture inside this ADuM3400CRWZ-RL eliminates LED aging and gives tighter baud-rate timing, important for long-lifetime industrial equipment.
Empfohlen
Industrial Fieldbus (Modbus / CAN) Interface
The ADUM3400CRWZ-RL supports isolated industrial fieldbus connections between Modbus RTU or CAN bus controllers and bus transceivers by placing its 2500Vrms barrier between the bus and the controller logic, with all four channels unidirectional in the same direction per the 4/0 specification. Per the ADI datasheet, the 25 kV/us CMTI rating and enhanced IEC 61000-4-x ESD protection are critical when the bus cable is exposed to ESD strikes or coupling transients. The 2.7V-5.5V supply range supports both 3.3V controllers and 5V transceivers.

Isolated Gate Drive Signal Path
For isolated gate-drive signal paths in motor-control inverters and Class-D amplifiers, the ADUM3400CRWZ-RL places its 2500Vrms barrier between low-voltage FPGA/MCU logic and the high-side gate driver referenced to the switching node. Per the ADI datasheet, the 25 kV/us minimum CMTI is the headline parameter here - it ensures logic transitions are not corrupted by dv/dt events at the switching node. The 90 Mbps data rate supports PWM frequencies above 1 MHz, and the wide-body SOIC's 8 mm creepage matches 600V-1.7 kV motor systems per IEC 61800.
Empfohlen
Isolated ADC Data Acquisition
The ADUM3400CRWZ-RL isolates ADC data outputs from a noisy industrial environment by placing its 2500Vrms barrier between the ADC front-end and the FPGA, with all four channels unidirectional in the same direction per the 4/0 specification. Per the ADI datasheet, the 90 Mbps speed supports ADC sample rates above 10 MSPS, and the 25 kV/us CMTI rating keeps the data digitized without false edges even during high-side switching. The wide-body SOIC footprint and 2.7V-5.5V supplies match both 3.3V ADCs and 5V FPGAs used in parallel-bus data systems.
Empfohlen
Isolated Sensor Signal Conditioning
The ADUM3400CRWZ-RL isolates sensor signal conditioning between high-voltage current/voltage sensors and low-voltage signal conditioning circuits by placing its 2500Vrms barrier with 4/0 channel directionality on the data path. Per the ADI datasheet, the 90 Mbps data rate supports wide-bandwidth current sensors and shunt monitors, the 25 kV/us CMTI rating rejects ground bounce in switch-mode sensor front-ends, and the wide-body SOIC footprint supports the 8 mm creepage required by IEC 61010 measurement systems.

Wichtigste Unterscheidungsmerkmale
- Highest speed in legacy ADuM340x family (vs. ADUM3400BRWZ)
- Lower quiescent current at same length (vs. ADUM140E1BRWZ)
- Wide-body footprint vs narrow-body footprint (vs. ADUM1400CRW)
- Unidirectional 4/0 vs mixed directionality (vs. ADUM3401CRWZ)
Designhinweise
Maintain at least 8 mm of external clearance between the high-voltage side and low-voltage side copper for the wide-body SOIC footprint to satisfy reinforced isolation per IEC 60730-1. Per the ADI datasheet, both VDD1 (pin 1) and VDD2 (pin 15) must be bypassed with 0.1 uF ceramic capacitors placed as close as possible to the IC pins. The DISABLE pin (pin 4) should be tied to GND1 via 100 kohm if unused to avoid floating-input noise pickup.
Do not route any high-speed signal traces under or directly adjacent to the isolation barrier in the SOIC wide-body package. Per the ADI datasheet, all four data channels are unidirectional (4/0 directionality), so a return-path signal such as SPI MISO requires a second isolator or use of the ADuM3402 instead. Exceeding 35 kV/us CMTI requires the enhanced CMTI family (ADuM140E) instead.
Per the ADI datasheet, the data channel propagation delay is typically 32 ns at 5V operation with skew of less than 5 ns between channels. Use impedance-controlled traces on the high-speed data lines if the bus is longer than 50 mm, and provide 0.1 uF bypass on VDD1 and VDD2 to suppress switching-edge current spikes that could otherwise couple across the isolation barrier.
Per the ADI datasheet, the ADUM3400CRWZ-RL draws a maximum of 1.4 mA quiescent current per channel at 5V for 0-2 Mbps operation, scaling up to ~5 mA per channel at 90 Mbps. Use a low-noise LDO for both VDD1 and VDD2 to minimize jitter from supply ripple, and select the LDO with 100 mA of headroom to support four channels of full switching load simultaneously.
