Analog Devices Inc. ADUM6202ARIZ-RL

Overview

ADUM6202ARIZ-RL from Analog Devices is a dual-channel, 5 kV rms reinforced digital isolator with integrated isoPower® dc-to-dc converter delivering up to 400 mW isolated output power at 5 V or 3.3 V, supporting 25 Mbps NRZ data rates and operating across −40°C to +105°C. It enables compact, self-powered isolation in industrial RS-485 transceivers and PLC I/O modules.

For engineers reviewing the ADUM6202ARIZ-RL datasheet, ADUM6202ARIZ-RL pinout, ADUM6202ARIZ-RL application, or ADUM6202ARIZ-RL equivalent, key selection factors include its 5 kV rms UL/IEC/VDE-certified reinforced insulation, 846 V peak VIORM, dual-channel directionality (VOA/VIB inputs → VIA/VOB outputs), and 16-lead SOIC wide-body (RI-16-1) package with 8.3 mm creepage.

Technical Context

The ADUM6202ARIZ-RL implements iCoupler® chip-scale transformer technology for both signal isolation and magnetic power transfer, eliminating external isolated DC/DC converters. Its isoPower core operates at 625 kHz PWM frequency with 180 MHz oscillator frequency and supports three input/output voltage configurations: 5 V/5 V, 5 V/3.3 V, and 3.3 V/3.3 V.

It features independent undervoltage lockout (2.4 V/2.7 V hysteresis) on both primary (VDD1) and secondary (VISO) supplies, programmable output voltage selection via VSEL, and regulation control (RCIN/RCSEL) for master/slave operation. Channel timing includes 45 ns typical propagation delay and ≤6 ns pulse width distortion at 25 Mbps.

FAQ

What is the maximum isolated output power of the ADUM6202ARIZ-RL?

The ADUM6202ARIZ-RL delivers up to 400 mW of regulated isolated output power at 5.0 V when supplied with a 5.0 V input, or 330 mW at 3.3 V output from a 5.0 V input. At 3.3 V input, it provides 132 mW at 3.3 V output. These values are specified in Table 1 of the datasheet and depend on input/output voltage combinations and thermal conditions.

Does the ADUM6202ARIZ-RL support both 3.3 V and 5 V isolated output voltages?

Yes, the ADUM6202ARIZ-RL supports selectable isolated output voltages of either 3.3 V or 5.0 V via the VSEL pin: tie VSEL to GNDISO for 3.3 V VISO, or tie VSEL to VISO for 5.0 V VISO. This configuration is confirmed in the Functional Block Diagram (Figure 1) and Pin Function Descriptions (Table 21).

What is the channel direction configuration of the ADUM6202ARIZ-RL?

The ADUM6202ARIZ-RL has fixed directional mapping: VIA (Pin 3) drives VOA (Pin 14), and VIB (Pin 4) drives VOB (Pin 13). This is explicitly shown in Figure 4 of the datasheet and distinguishes it from ADUM6200 (VIA→VOA/VIB→VOB) and ADUM6201 (VIA→VOB/VIB→VOA).

Which safety certifications apply to the ADUM6202ARIZ-RL package?

The ADUM6202ARIZ-RL in the RI-16-1 package is certified to DIN V VDE V 0884-10:2006-12 (reinforced insulation, 846 V peak VIORM), IEC 60601-1 (250 V rms), and IEC 60950-1 (400 V rms). These approvals are documented in Table 15 and the Regulatory Information section of the Rev. C datasheet.

Can the ADUM6202ARIZ-RL operate at 105°C ambient temperature?

Yes, the ADUM6202ARIZ-RL is rated for −40°C to +105°C ambient operation. However, at 105°C, the maximum load current must be reduced per the Thermal Derating Curve (Figure 5) and Table 19, which specifies derated output current limits to maintain safe junction temperature and reliability.
