Product details
Overview
ADuM6211BRSZ from Analog Devices is a dual-channel digital isolator with integrated isoPower® DC-to-DC converter, providing galvanic isolation and regulated 3.3 V or 5.0 V isolated supply up to 150 mW. It delivers two unidirectional signal channels (A input → A output, B input → B output), supports data rates up to 100 Mbps (NRZ), and operates across −40°C to +105°C in industrial PLCs and isolated sensor interfaces.
For engineers reviewing the ADuM6211BRSZ datasheet, ADuM6211BRSZ pinout, ADuM6211BRSZ application, or ADuM6211BRSZ equivalent, key selection criteria include its 20-lead SSOP package with 5.3 mm creepage, reinforced 3750 Vrms isolation rating, VSEL-programmable VISO output, and high common-mode transient immunity (>25 kV/µs) critical for noisy industrial environments.
Technical Context
The ADuM6211BRSZ implements iCoupler® chip-scale transformer technology for both signal isolation and power transfer, eliminating external isolated DC-DC converters. Its isoPower section uses 125 MHz switching frequency and 600 kHz PWM control to deliver regulated VISO with load regulation ≤3% and output ripple ≤75 mVp-p.
Signal channels feature independent VDD1/VDD2 supplies (3.135–5.5 V), programmable VISO via VSEL resistor network, and PDIS-controlled power disable. Pin configuration assigns VIA/VIB as inputs and VOA/VOB as outputs-distinct from ADuM6210 (dual input) and ADuM6212 (dual output)-enabling asymmetric bidirectional communication paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 100 Mbps NRZ - enables high-speed SPI (≤15 MHz) and fast digital interface isolation without timing bottlenecks. |
| VISO Output | Programmable 3.3 V or 5.0 V - set via external VSEL resistor divider; supports mixed-voltage system partitioning across isolation barrier. |
| Isolation Rating | 3750 Vrms for 1 min (UL 1577), VIORM = 849 Vpeak (VDE 0884-10) - certified reinforced insulation for safety-critical industrial applications. |
| Common-Mode Immunity | >25 kV/µs - maintains signal integrity during fast transients in motor drives and power supply feedback loops. |
| Package | 20-lead SSOP, 5.3 mm creepage - meets IPC-2221 creepage requirements for 250 Vrms working voltage in pollution degree 2 environments. |
| Thermal Range | −40°C to +105°C ambient - validated operation at full performance in extended-temperature industrial enclosures. |
| Output Power | Up to 150 mW at 5 Vin/5 Vout - sufficient to power downstream logic (e.g., ADCs, gate drivers) without auxiliary isolated supply. |
Pinout & Package
ADuM6211BRSZ uses a 20-lead SSOP package (7.2 mm × 5.3 mm, 0.65 mm pitch) with input-side (P-side) and output-side (ISO-side) pins separated by ≥5.3 mm creepage distance. GNDP (Pins 2,5,6,10) and GNDISO (Pins 11,15,16,19) are internally connected groups requiring low-inductance PCB grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 20 | VDD1 / VDD2 | Independent logic supplies for side 1 (input) and side 2 (output); each supports 3.135–5.5 V - enables level-shifting between domains. |
| 3, 18 | VIA / VIA | Input A (Pin 3) and Input A (Pin 18) - dual-input assignment per datasheet Table 1 confirms ADuM6211 uses Pin 3 as VIA and Pin 18 as VIA (not VOA). |
| 4, 17 | VIB / VOB | Input B (Pin 4) and Output B (Pin 17) - asymmetric channel mapping defines directionality: A and B inputs on primary side, B output on secondary side. |
| 8 | PDIS | Active-low power disable - asserts high to enter standby mode, reducing IDDP(Q) to ≤12 mA and disabling VISO output. |
| 9 | VDDP | Primary isoPower input (3.135–5.5 V) - powers internal DC-DC converter; distinct from VDD1/VDD2 which power logic only. |
| 12 | VISO | Regulated isolated output (3.3 V or 5.0 V) - supplies external loads up to 30 mA; voltage set by VSEL resistor network to 1.25 V reference. |
| 13 | VSEL | Voltage select input - connects to resistor divider from VISO to GNDISO; determines VISO setpoint per Table 2 and Section "VSEL Resistor Network". |
Key Features
| Feature | Design Value |
|---|---|
| Integrated isoPower DC-DC converter | Eliminates need for external isolated supply; delivers up to 150 mW regulated VISO with soft-start to limit inrush current. |
| VSEL-programmable VISO | Configures output voltage to 3.3 V or 5.0 V using external resistors - supports flexible system-level voltage domain partitioning. |
| Asymmetric channel direction (I/O-I/O) | Pin 3=VIA (input), Pin 4=VIB (input), Pin 17=VOB (output), Pin 18=VIA (input) - enables dedicated input-only and output-only paths across barrier. |
| High CMTI & reinforced isolation | >25 kV/µs common-mode transient immunity and UL/VDE-certified 3750 Vrms - ensures robust operation in high-noise motor control and power conversion. |
| Thermal shutdown protection | Activates at 154°C junction temperature with 10°C hysteresis - prevents damage during overload or poor heatsinking conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel digital isolator with integrated DC-DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si88221ED-IS | 2-channel, 5 kVrms isolation, 50 mW VISO, fixed 3.3 V output, no VSEL | Limited to 3.3 V isolated supply; lower power output restricts use with higher-current peripherals | Select when 3.3 V only is required and lower cost outweighs programmability and power headroom. |
| ISO7821FDWWR | 2-channel, 8000 Vpk reinforced isolation, no integrated DC-DC; requires external isolated supply | Higher isolation rating but adds complexity/cost of external DC-DC and layout constraints for emissions | Select when maximum isolation voltage is mandatory and external power design is already established. |
Compared with Si88221ED-IS and ISO7821FDWWR, ADuM6211BRSZ uniquely combines VSEL-programmable VISO (3.3 V/5.0 V), 150 mW output, and asymmetric I/O mapping in a single 20-lead SSOP - simplifying designs needing flexible isolated power and directional signal routing without external components.

FAQ
What is the maximum data rate supported by ADuM6211BRSZ?
ADuM6211BRSZ supports up to 100 Mbps NRZ data rate under C-grade specifications with propagation delay ≤20 ns and pulse width distortion ≤2 ns. This enables reliable high-speed SPI communication (up to 15 MHz) and real-time control signal transmission across the isolation barrier in industrial applications.
How is the isolated output voltage (VISO) configured on ADuM6211BRSZ?
VISO on ADuM6211BRSZ is configured using an external resistor divider connected between VISO (Pin 12) and GNDISO (Pin 11/15/16/19), with the midpoint tied to VSEL (Pin 13). The divider sets VISO to either 3.3 V (R1=10 kΩ, R2=16.9 kΩ) or 5.0 V (R1=10 kΩ, R2=30.9 kΩ), matching the internal 1.25 V reference.
What is the purpose of the PDIS pin on ADuM6211BRSZ?
The PDIS pin (Pin 8) on ADuM6211BRSZ is an active-low power disable control. When pulled high, it places the isoPower DC-DC converter in low-power standby mode, reducing quiescent input current (IDDP(Q)) to ≤12 mA and disabling VISO output - useful for power-gated system states or thermal management.
Does ADuM6211BRSZ require external bypass capacitors, and if so, where?
Yes, ADuM6211BRSZ requires 0.1 µF || 10 µF ceramic capacitors between VISO (Pin 12) and GNDISO (Pin 11/15/16/19) to suppress output ripple (≤75 mVp-p) and noise (≤200 mVp-p). Additional 0.1 µF capacitors are recommended near VDD1 (Pin 1), VDD2 (Pin 20), and VDDP (Pin 9) to stabilize logic and power supply rails.
What safety certifications does ADuM6211BRSZ hold?
ADuM6211BRSZ holds UL 1577 recognition (3750 Vrms, File E214100), CSA Component Acceptance Notice 5A (File 205078), and VDE certification to DIN V VDE V 0884-10:2006-12 (VIORM = 849 Vpeak, File 2471900-4880-0001), confirming reinforced insulation for industrial safety standards.
