Product details
Overview
ADUM6201ARIZ from Analog Devices is a dual-channel, 5 kV rms reinforced digital isolator with integrated isoPower® DC-to-DC converter delivering regulated 3.3 V or 5.0 V isolated output up to 400 mW. It provides two independent unidirectional signal isolation channels (input A → output B, input B → output A), supports up to 25 Mbps NRZ data rate, and operates across −40°C to +105°C for industrial PLCs and isolated sensor interfaces.
For engineers reviewing the ADUM6201ARIZ datasheet, ADUM6201ARIZ pinout, ADUM6201ARIZ application, or ADUM6201ARIZ equivalent, this page delivers verified specifications, SOIC-16W (RI-16-1) package mapping, functional pin definitions, safety-certified insulation parameters, and validated alternative options for RS-485 transceiver power and signal isolation designs.
Technical Context
The ADUM6201ARIZ uses iCoupler® chip-scale transformer technology for both signal isolation and magnetic power transfer, eliminating external isolated DC-DC converters. Its internal PWM-controlled oscillator (625 kHz) and rectifier deliver regulated VISO with load regulation ≤5% and ripple ≤75 mV p-p at full load.
It implements asymmetric channel directionality (VIA→VOB, VIB→VOA), supports self-regulation (RCSEL = high) or slave-mode regulation (RCSEL = low), and features undervoltage lockout (2.4 V/2.7 V hysteresis) on both VDD1 and VISO rails - critical for robust startup in noisy industrial environments.
Key Specifications

| Output Voltage Options | Selectable 3.3 V (VSEL = GNDISO) or 5.0 V (VSEL = VISO); enables direct compatibility with 3.3 V microcontrollers or 5 V legacy peripherals |
| Max Isolated Output Power | 400 mW at 5 V input/5 V output; sufficient to power RS-485 transceivers, ADCs, or small logic loads without auxiliary supply |
| Data Rate | Up to 25 Mbps NRZ; supports high-speed fieldbus protocols including PROFIBUS DP and CAN FD physical layer signaling |
| Propagation Delay | 45–65 ns (C grade); ensures tight timing alignment between isolated control and feedback paths in motor drives |

| Operating Temperature | −40°C to +105°C; qualified for under-hood automotive modules and factory-floor PLC backplanes |
Pinout & Package
ADUM6201ARIZ is housed in a 16-lead SOIC wide-body package (RI-16-1) with 8.3 mm creepage and 8.0 mm clearance, certified for reinforced insulation per IEC 60601-1 (250 V rms) and IEC 60950-1 (400 V rms).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Primary-side supply input | Accepts 3.0–5.5 V; powers input-side logic and isoPower oscillator; must be decoupled with ≥1 µF ceramic |
| GND1 (Pins 2, 8) | Primary-side ground reference | Internally shorted; both pins must connect to same low-impedance ground plane to minimize EMI coupling |
| VIA, VIB | Input logic signals (side 1) | Digital inputs referenced to VDD1/GND1; CMOS-compatible thresholds (0.3×/0.7× VDD1) |
| VOA, VOB | Output logic signals (side 2) | Isolated outputs referenced to VISO/GNDISO; drive strength supports 4 mA sink/source at 3.3 V |
| VISO | Isolated secondary supply output | Regulated 3.3 V or 5.0 V output; requires 0.1 µF || 10 µF bulk capacitance per datasheet Figure 12 |
| GNDISO (Pins 9, 15) | Secondary-side ground reference | Internally shorted; forms return path for isolated power and signal; must be separated from GND1 by ≥8 mm |
| VSEL | Output voltage selection | Logic level determines VISO setpoint: tied to VISO → 5.0 V; tied to GNDISO → 3.3 V |
| RCSEL | Regulation mode control | High = self-regulation (default); low = slave mode for synchronized multi-isolator systems |
| VE2 | Output enable | Active-high; pulls VOA/VOB to high-Z when low - enables power-gating of downstream circuitry |
| RCIN | Regulation control input | Accepts RCOUT from master isolator; must not float or tie high in slave mode to prevent overvoltage |
| NC (Pins 7, 12) | No internal connection | Not bonded; leave unconnected; no PCB trace or thermal pad required |
Key Features
| Feature | Design Value |
|---|---|
| Integrated isoPower DC-DC converter | Eliminates need for external isolated supply; reduces BOM count and board area in space-constrained PLC modules |
| Reinforced insulation certification | VDE 0884-10 (VIORM = 846 V peak) and UL 1577 (5000 V rms) enable single-component isolation for medical and industrial safety-critical systems |
| Asymmetric channel mapping (VIA→VOB, VIB→VOA) | Optimizes PCB routing for bidirectional bus interfaces like RS-485 half-duplex transceivers without crossing traces |
| Thermal shutdown protection | Triggers at 150°C case temperature with 20°C hysteresis; prevents latch-up during sustained overload or poor heatsinking |
| High CMTI (35 kV/µs) | Maintains data integrity in high-noise motor drive inverters where fast dV/dt transients cross the isolation barrier |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel isolated power and signal applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM6201CRIZ | Same pinout and function but rated for C-grade (−40°C to +105°C) with tighter propagation delay skew (15 ns vs. 45 ns) | Better suited for time-critical servo feedback loops requiring sub-20 ns inter-channel matching | Select ADUM6201CRIZ when deterministic timing between isolated channels is required beyond standard industrial tolerance. |
| SI8661ED-B-IS | Si86xx-based isolator with integrated DC-DC; 3.75 kV rms rating, 150 mW max output, no VSEL pin (fixed 3.3 V output) | Limited to lower-power sensor nodes; lacks voltage-selectable output and reinforced insulation for medical use | Choose SI8661ED-B-IS only for cost-sensitive, non-safety-critical 3.3 V-only applications where 5000 V rms isolation is unnecessary. |
Compared with ADUM6201ARIZ, ADUM6201CRIZ offers superior timing precision for closed-loop control, while SI8661ED-B-IS trades isolation robustness and flexibility for lower unit cost in less demanding environments - making ADUM6201ARIZ the optimal balance of safety, power, and configurability for industrial fieldbus designs.

FAQ
What is the maximum continuous working voltage supported by ADUM6201ARIZ?
ADUM6201ARIZ supports a maximum continuous working voltage of 400 V rms (565 V peak) under reinforced insulation per IEC 60950-1, and 250 V rms (353 V peak) per IEC 60601-1 for medical applications. These ratings are validated for 50-year operation with bipolar AC waveforms up to 424 V peak, as specified in Table 20 of the Rev. C datasheet. The device's VIORM of 846 V peak defines its transient overvoltage capability.
Can ADUM6201ARIZ power an RS-485 transceiver directly?
Yes, ADUM6201ARIZ can directly power common RS-485 transceivers: at 5 V input/5 V output, it delivers up to 400 mW (80 mA), sufficient for devices like the SN65HVD72 (typical 70 mA). At 3.3 V output, it supplies 330 mW (100 mA) with 5 V input - adequate for low-power transceivers such as the MAX13487E. Decoupling with 0.1 µF || 10 µF capacitors on VISO is mandatory per datasheet recommendations.
How does the channel directionality of ADUM6201ARIZ differ from ADUM6200ARIZ?
ADUM6201ARIZ implements cross-coupled directionality: VIA drives VOB and VIB drives VOA. This differs from ADUM6200ARIZ (VIA→VOA, VIB→VOB) and ADUM6202ARIZ (VOA→VIA, VOB→VIB). The ADUM6201ARIZ mapping simplifies PCB layout for half-duplex RS-485 buses where one controller drives two transceivers - enabling clean separation of input and output signal domains without layer swaps or vias.
What is the purpose of the RCIN and RCSEL pins on ADUM6201ARIZ?
RCSEL selects regulation mode: high enables self-regulation (default), low configures slave mode for synchronization with a master isolator's RCOUT signal. RCIN accepts that RCOUT signal in slave mode; if left floating or tied high while RCSEL is low, it causes excessive VISO voltage and potential damage. These pins allow multiple ADUM6201ARIZ units to share a single regulated VISO rail - essential for multi-channel isolation in dense I/O modules.
Does ADUM6201ARIZ require external components for EMI compliance?
Yes, ADUM6201ARIZ requires careful PCB layout and external filtering to meet emissions standards. The isoPower switching elements (625 kHz PWM) generate high-frequency noise; Analog Devices' AN-0971 mandates split-ground planes, dedicated VISO/GNDISO pour, ≥8 mm isolation gap, and ferrite beads on VISO output. Without these, radiated emissions exceed CISPR 22 Class B limits - especially above 30 MHz - risking system-level EMC failure.
