Product details

Overview

ADUM2201ARIZ-RL from Analog Devices is a dual-channel digital isolator based on iCoupler® transformer technology, providing reinforced 5 kV_rms isolation, 10 Mbps data rate, and 3.3 V/5 V level translation across the barrier. It operates from 3.0 V to 5.5 V on both sides, supports −40°C to +105°C ambient, and delivers precise timing with ≤3 ns pulse width distortion - used in isolated RS-485 transceivers and medical power supply feedback loops.

For engineers reviewing the ADUM2201ARIZ-RL datasheet, ADUM2201ARIZ-RL pinout, ADUM2201ARIZ-RL application, or ADUM2201ARIZ-RL equivalent, key selection criteria include reinforced insulation rating (VIORM = 645 V_peak), channel directionality (A-output/B-input), mixed-voltage operation capability, and SOIC-Wide (RI-16-2) package creepage compliance for IEC 60601-1 and IEC 62368-1 safety-critical systems.

Technical Context

The ADUM2201ARIZ-RL implements two independent unidirectional isolation channels using monolithic air-core transformers, with Channel A configured as output-only (VIA → VOA) and Channel B as input-only (VIB → VOB). Its patented refresh circuit ensures DC correctness during idle periods and power transitions without external components.

It achieves high common-mode transient immunity (>25 kV/µs) via differential transformer coupling and internal noise rejection, while maintaining tight timing control: propagation delay skew ≤15 ns (codirectional), pulse width distortion ≤3 ns, and channel-to-channel matching ≤3 ns - enabling reliable synchronization in motor drive gate driver interfaces and isolated ADC/DAC data links.

9, 16	GND2	Output-side ground reference; internally shorted - must connect to isolated GND2 plane
10, 11, 15	NC	No internal connection; keep unconnected and unstubbed
12	VOB	Channel B output (isolated side); complements VIB input for full-duplex isolation paths
13	VIA	Channel A input (non-isolated side); accepts CMOS-level signals referenced to GND1
14	VDD2	Output-side supply (3.0–5.5 V); requires local 0.01–0.1 µF bypass capacitor to GND2

FAQ

What is the isolation voltage rating of ADUM2201ARIZ-RL and which safety standards does it meet?

ADUM2201ARIZ-RL is rated for 5000 V_rms isolation for 1 minute per UL 1577 and features reinforced insulation certified to DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 645 V_peak. It meets IEC 60601-1 (2 MOPP), IEC 62368-1, IEC 61010-1, and CQC GB4943.1 - validated for use in medical, industrial, and test equipment where galvanic separation and safety compliance are mandatory. The ADUM2201ARIZ-RL achieves this in its RI-16-2 package with 8.7 mm creepage.

How is channel directionality configured in ADUM2201ARIZ-RL compared to ADUM2200ARIZ-RL?

ADUM2201ARIZ-RL has fixed unidirectional channel assignment: Pin 4 (VOA) and Pin 12 (VOB) are outputs, while Pin 13 (VIA) and Pin 5 (VIB) are inputs - enabling A-output/B-input configuration. In contrast, ADUM2200ARIZ-RL assigns Pins 4 and 5 as inputs (VIA/VIB) and Pins 12 and 13 as outputs (VOB/VOA). This directional split makes ADUM2201ARIZ-RL ideal for asymmetric signal flow such as isolated UART TX/RX or PWM enable/control paths. The ADUM2201ARIZ-RL pinout is explicitly defined in Analog Devices' Rev. H datasheet Figure 5.

Does ADUM2201ARIZ-RL support mixed-voltage operation, and what are the valid supply combinations?

Yes, ADUM2201ARIZ-RL supports mixed-voltage operation across the isolation barrier: VDD1 and VDD2 may each be independently set to 3.0–5.5 V, enabling 3.3 V ↔ 5 V level translation. Valid configurations include 3.3 V on Side 1 / 5 V on Side 2, or 5 V on Side 1 / 3.3 V on Side 2 - with full 10 Mbps data rate maintained in all cases. Electrical characteristics for these modes are specified in Tables 7–12 of the ADUM2201ARIZ-RL datasheet. This eliminates external level shifters in mixed-rail systems.

What is the maximum continuous working voltage for ADUM2201ARIZ-RL, and how is it determined?

The maximum continuous working voltage for ADUM2201ARIZ-RL is 456 V_rms (VIOWM), derived from its VIORM = 645 V_peak rating per DIN EN IEC 60747-17. This value applies to reinforced insulation under pollution degree 2 and altitudes ≤2000 m, and is validated for bipolar waveforms. It is not a peak surge rating - transient overvoltages up to 10,000 V_peak (VIOSM) are allowed per IEC 61000-4-5, but continuous AC or DC bias must remain within VIOWM. The ADUM2201ARIZ-RL datasheet Table 19 specifies this limit explicitly.

Is ADUM2201ARIZ-RL suitable for automotive applications, and what qualifications does it hold?

ADUM2201ARIZ-RL is qualified for automotive applications per AEC-Q100 stress testing requirements, supporting operation from −40°C to +105°C (A Grade). While it carries no specific automotive part number suffix, its qualification extends to subsystems including battery monitors, motor control units, and charging interface modules in hybrid electric vehicles. It meets IEC 60601-1 for medical use and IEC 62368-1 for general electronics - but for ASIL-B/C functional safety systems, external diagnostics or redundancy must be implemented per ISO 26262, as ADUM2201ARIZ-RL itself is not ASIL-certified. The ADUM2201ARIZ-RL datasheet confirms automotive qualification on page 20.
