Analog Devices Inc. ADUM6201CRWZ-RL

Overview

ADUM6201CRWZ-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 NRZ), operates from −40°C to +105°C, and features 846 V_PEAK working voltage per VDE 0884-10. It is used in isolated RS-485 transceivers and industrial PLC I/O modules where space-constrained, low-power galvanic separation is required.

For engineers reviewing the ADUM6201CRWZ-RL datasheet, ADUM6201CRWZ-RL pinout, ADUM6201CRWZ-RL application, or ADUM6201CRWZ-RL equivalent, key selection considerations include its integrated 5 kV isolation barrier, self-regulated isolated supply capability, 25 Mbps channel bandwidth, 3.3/5.0 V output configurability via VSEL, and compliance with IEC 60601-1 (250 V_RMS) and IEC 60950-1 (400 V_RMS) for medical and industrial safety-critical systems.

Technical Context

The ADUM6201CRWZ-RL implements iCoupler® transformer-based isolation for both data signals and power transfer, eliminating external isolated DC-DC converters. Its isoPower core uses high-frequency switching (625 kHz PWM, 180 MHz oscillator) with magnetic coupling across the isolation barrier, requiring careful PCB layout per AN-0971 to meet emissions standards.

It supports three input/output supply configurations: 5 V → 5 V (400 mW), 5 V → 3.3 V (330 mW), or 3.3 V → 3.3 V (132 mW), with VSEL pin selecting secondary output voltage and RCSEL enabling self-regulation or slave-mode operation. Propagation delay skew is ≤6 ns (codirectional) and ≤15 ns (opposing), with common-mode transient immunity of 25–35 kV/µs.

FAQ

What is the maximum isolated output power of the ADUM6201CRWZ-RL?

The ADUM6201CRWZ-RL delivers up to 400 mW of regulated isolated output power when configured for 5 V input → 5 V output. At 5 V input → 3.3 V output, it provides 330 mW; at 3.3 V input → 3.3 V output, it delivers 132 mW. These values are specified in Table 1 of the Rev. C datasheet and assume proper decoupling (0.1 µF || 10 µF) and thermal management per the thermal derating curve in Figure 5.

How does the ADUM6201CRWZ-RL differ from the ADUM6201ARWZ-RL?

The ADUM6201CRWZ-RL is the C-grade version, rated for 25 Mbps data rate across −40°C to +105°C, while the ADUM6201ARWZ-RL is A-grade with only 1 Mbps maximum data rate. Both share identical pinout, isolation rating, and isoPower functionality, but the C-grade part supports high-speed industrial communications such as fast RS-485 or SPI, whereas the A-grade is limited to low-speed control signaling.

Can the ADUM6201CRWZ-RL be used in medical applications requiring IEC 60601-1 compliance?

Yes - the ADUM6201CRWZ-RL is certified for reinforced insulation per IEC 60601-1 with a 250 V_RMS maximum working voltage (8 mm package, RI-16-1) and carries VDE certification (DIN V VDE V 0884-10:2006-12). Its 846 V_PEAK VIORM and 5000 V_RMS withstand voltage meet essential safety requirements for patient-connected equipment when implemented per the manufacturer's layout guidelines.

What is the function of the VE2 pin on the ADUM6201CRWZ-RL?

The VE2 pin on the ADUM6201CRWZ-RL is an output enable control: when pulled high or left floating, the isolated outputs VOA and VOB are active; when pulled low, they enter a high-impedance (high-Z) state. This allows dynamic power gating of downstream circuitry, supports bus-sharing topologies, and enables safe power sequencing during system startup or fault recovery.

Does the ADUM6201CRWZ-RL require external components for its isolated DC-DC converter?

Yes - the ADUM6201CRWZ-RL requires external 0.1 µF and 10 µF capacitors on the VISO/GNDISO rails (CBO) for output filtering, as specified in Tables 2–10 and Figure 18 of the datasheet. No inductors or transformers are needed, but improper capacitor selection or placement increases output ripple and noise beyond the 50–75 mV_p-p specification, potentially affecting downstream logic stability.
