Product details
Overview
ADUM6201ARWZ-RL 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 (data rate up to 25 Mbps), operates across −40°C to +105°C, and features 846 V peak reinforced insulation per VDE V 0884-10. It is used in industrial PLCs and isolated RS-485 transceiver interfaces requiring compact, self-powered isolation.
For engineers reviewing the ADUM6201ARWZ-RL datasheet, ADUM6201ARWZ-RL pinout, ADUM6201ARWZ-RL application, or ADUM6201ARWZ-RL equivalent, key selection considerations include its integrated 3.3/5.0 V isolated supply capability, 25 Mbps channel data rate, 5 kV rms UL/CSA/VDE safety ratings, SOIC-16 wide-body (RI-16-1) package with 8.3 mm creepage, and dual-channel directionality (VIA→VOB, VIB→VOA).
Technical Context
The ADUM6201ARWZ-RL implements iCoupler® chip-scale transformer technology for both signal isolation and power transfer, eliminating external isolated DC-DC converters. Its isoPower architecture uses high-frequency switching (625 kHz PWM, 180 MHz oscillator) with internal regulation controlled by VSEL and RCSEL pins.
It supports three input/output voltage configurations: 5 V input → 5 V isolated output (400 mW), 5 V input → 3.3 V isolated output (100 mA), or 3.3 V input → 3.3 V isolated output (40 mA). Channel directionality is fixed as Input A → Output B and Input B → Output A, confirmed by functional block diagram and pinout.

Pinout & Package
ADUM6201ARWZ-RL is housed in a 16-lead SOIC wide-body package (RI-16-1) with reinforced insulation, 8.3 mm creepage, and 8.0 mm clearance. Pin 1–8 form the primary (input) side; Pins 9–16 form the secondary (output/isolated) side. GND1 (Pins 2,8) and GNDISO (Pins 9,15) are internally shorted pairs requiring common grounding on respective sides.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 (Pin 1) | Primary supply input | 3.0–5.5 V logic-side power; powers input circuitry and isoPower primary winding |
| VIA (Pin 3), VIB (Pin 4) | Logic inputs | Primary-side digital inputs; drive isolated channels A and B respectively |
| RCSEL (Pin 6) | Regulation mode control | High = self-regulation; low = slave mode (external regulation required) |
| VSEL (Pin 11) | Output voltage select | VSEL = VISO → 5.0 V VISO; VSEL = GNDISO → 3.3 V VISO |
| VOA (Pin 14), VOB (Pin 13) | Isolated outputs | Secondary-side outputs; ADUM6201ARWZ-RL has VIA→VOB and VIB→VOA directionality |
| VISO (Pin 16) | Isolated supply output | Regulated 3.3 V or 5.0 V output; supplies isolated-side logic and loads up to 100 mA (5 V→3.3 V mode) |
| GNDISO (Pins 9,15) | Secondary ground | Reference for VISO and isolated outputs; must be separated from primary ground |
Key Features
| Feature | Design Value |
|---|---|
| Integrated isoPower DC-DC converter | Eliminates need for external isolated power supply; reduces BOM count and PCB area in space-constrained designs |
| Reinforced 5 kV rms isolation | Meets IEC 60601-1 (250 V rms) and IEC 60950-1 (400 V rms) for medical and industrial safety-critical systems |
| Dual-channel directional configuration | Fixed VIA→VOB / VIB→VOA routing enables deterministic signal flow in bidirectional bus interfaces like RS-485 |
| High CMTI (35 kV/µs) | Prevents data corruption during fast transients in motor drives and power inverters with high dv/dt noise |
| Thermal protection with derating curve | Enables reliable operation up to +105°C ambient; safe operating current decreases predictably above 100°C |
Applications
| Industrial PLC Digital I/O Isolation | Isolated RS-485 Transceiver Power & Signal Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel isolated DC-DC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM6201BRWZ-RL | Same pinout and function; higher-grade C specification with 25 Mbps guaranteed (vs. ADUM6201ARWZ-RL's 1 Mbps min/25 Mbps typical) | Required for designs needing guaranteed 25 Mbps operation over full temperature range | Select ADUM6201BRWZ-RL when 25 Mbps must be maintained at −40°C or +105°C without derating |
| SI88222ED-IS | 2-channel isolator with integrated 5 V DC-DC (300 mW); lower CMTI (20 kV/µs); different pinout (SOIC-16 but non-compatible) | Suitable for cost-sensitive industrial I/O where 35 kV/µs CMTI is not mandatory | Choose SI88222ED-IS only if redesigning PCB layout is acceptable and 20 kV/µs CMTI suffices |
Compared with ADUM6201ARWZ-RL, the ADUM6201BRWZ-RL guarantees full-speed operation across temperature, while SI88222ED-IS trades CMTI and pin compatibility for lower unit cost-neither is pin-compatible, requiring layout changes and revalidation.

FAQ
What is the maximum isolated output power of the ADUM6201ARWZ-RL?
The ADUM6201ARWZ-RL delivers up to 400 mW when configured for 5 V input → 5 V isolated output. In 5 V input → 3.3 V output mode, it supplies up to 100 mA (330 mW), and in 3.3 V input → 3.3 V mode, up to 40 mA (132 mW). These values are specified in Table 1 of the ADUM6201ARWZ-RL datasheet and depend on input/output voltage combination and thermal conditions.
How does the ADUM6201ARWZ-RL differ from the ADUM6200 and ADUM6202 variants?
The ADUM6201ARWZ-RL has fixed channel directionality: VIA drives VOB and VIB drives VOA. In contrast, ADUM6200ARWZ-RL routes VIA→VOA and VIB→VOB, while ADUM6202ARWZ-RL routes VOA→VIA and VOB→VIB (reverse direction). All three share identical isolation rating, power specs, and package-only signal path direction differs, as shown in Figures 2–4 of the ADUM6201ARWZ-RL datasheet.
Can the ADUM6201ARWZ-RL operate with a 3.3 V primary supply?
Yes, the ADUM6201ARWZ-RL supports 3.3 V primary operation (VDD1 = 3.0–3.6 V) with corresponding 3.3 V isolated output (VISO) when VSEL = GNDISO. In this mode, it delivers up to 40 mA (132 mW) at 3.3 V. The ADUM6201ARWZ-RL datasheet specifies full electrical characteristics for 3.3 V input in Tables 6–9, including reduced IDD1 and IISO limits versus 5 V operation.
What safety certifications apply to the ADUM6201ARWZ-RL in the RI-16-1 package?
The ADUM6201ARWZ-RL in the RI-16-1 package holds VDE V 0884-10 (reinforced insulation, 846 V peak), UL 1577 (5000 V rms), CSA Component Acceptance Notice #5A, and IEC 60950-1 (400 V rms) and IEC 60601-1 (250 V rms) approvals. These are documented in Table 15 and Section 8 of the ADUM6201ARWZ-RL datasheet, with test voltages and conditions explicitly tied to the RI-16-1 variant.
Is external filtering required on the VISO output of the ADUM6201ARWZ-RL?
Yes, the ADUM6201ARWZ-RL requires 0.1 µF || 10 µF ceramic + bulk capacitance on VISO per datasheet recommendations (Table 2, footnote). This minimizes output ripple (≤50 mV p-p in 3.3 V mode) and noise (≤130 mV p-p), ensuring stable operation of downstream ICs. Omitting this filter risks violating output regulation specs and increasing EMI emissions from the isoPower switching circuit.
