Analog Devices Inc. ADUM6202CRIZ

Overview

ADUM6202CRIZ 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 from −40°C to +105°C. It enables compact isolated RS-485 transceiver and industrial PLC I/O designs without external isolated power supplies.

For engineers reviewing the ADUM6202CRIZ datasheet, ADUM6202CRIZ pinout, ADUM6202CRIZ application, or ADUM6202CRIZ equivalent, key selection criteria include its 5 kV rms isolation rating, dual-channel directionality (VOA/VIB inputs → VIA/VOB outputs), 846 V peak VIORM, 35 kV/µs common-mode transient immunity, and SOIC-16 wide-body RI-16-1 package with 8.3 mm creepage.

Technical Context

The ADUM6202CRIZ implements iCoupler® transformer-based isolation for both signal channels and the on-chip dc-to-dc converter, using high-frequency switching (625 kHz PWM, 180 MHz oscillator) to transfer power across the barrier. Its internal architecture integrates two independent unidirectional logic channels with fixed input-to-output directionality (Pin 3/4 → Pin 14/13).

It supports three operating configurations: 5 V input → 5 V isolated output (400 mW), 5 V input → 3.3 V isolated output (100 mA max), or 3.3 V input → 3.3 V isolated output (40 mA max). Regulation is set by VSEL (Pin 11) and controlled via RCSEL (Pin 6) for self- or slave-mode operation.

Key Specifications

Pinout & Package

ADUM6202CRIZ uses a 16-lead SOIC wide-body package (RI-16-1) with reinforced insulation, 8.3 mm minimum creepage, and 8.0 mm clearance. Pins are grouped into primary-side (1–8) and secondary-side (9–16) domains with internal ground shorts (GND1: Pins 2 & 8; GNDISO: Pins 9 & 15).

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-channel isolated power applications.

Compared with ADUM6202ARIZ, the ADUM6202CRIZ trades minor timing precision for broader availability and lower unit cost, while versus SI88222ED-IS it delivers full integration at lower total system BOM cost and design effort - making it the preferred choice for standard industrial isolation with integrated power.

FAQ

What is the maximum isolated output current supported by ADUM6202CRIZ?

The ADUM6202CRIZ supports up to 80 mA at 5 V output (400 mW), 100 mA at 3.3 V output (when supplied with 5 V input), or 40 mA at 3.3 V output (when supplied with 3.3 V input). These values are specified in Tables 3, 7, and 11 of the Rev. C datasheet and reflect the maximum load current before regulation degrades beyond 5% load regulation error. Exceeding these limits risks undervoltage lockout or thermal shutdown.

How does ADUM6202CRIZ differ from ADUM6201CRIZ in pin configuration and signal direction?

The ADUM6202CRIZ has fixed input-to-output directionality: Pins 3 (VIA) and 4 (VIB) are inputs, while Pins 14 (VOA) and 13 (VOB) are outputs. In contrast, ADUM6201CRIZ swaps one channel - Pin 3 (VIA) is input, Pin 4 (VOB) is output, Pin 14 (VOA) is output, and Pin 13 (VIB) is input. This difference is explicitly shown in Figures 2–4 of the datasheet and affects PCB layout compatibility; ADUM6202CRIZ cannot substitute for ADUM6201CRIZ without redesign.

Can ADUM6202CRIZ operate with a 3.3 V primary supply and deliver 5 V isolated output?

No. The ADUM6202CRIZ cannot generate 5 V isolated output from a 3.3 V primary supply. Its isoPower architecture only supports VISO = VDD1 (3.3 V) or VISO = 5 V when VDD1 = 5 V. Table 6 confirms 3.3 V input yields only 3.3 V output; Table 10 shows 5 V input enables 3.3 V output, but no configuration achieves 5 V output from 3.3 V input. Attempting this violates absolute maximum ratings and may damage the device.

What safety certifications apply to ADUM6202CRIZ in the RI-16-1 package?

The ADUM6202CRIZ in the RI-16-1 package holds DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 certification for reinforced insulation (VIORM = 846 V peak), UL 1577 recognition (5000 V rms, 1 min), CSA Component Acceptance Notice #5A, and IEC 60601-1 approval for 250 V rms working voltage. These are documented in Table 15 and Section 8 of the Rev. C datasheet, with the * marking on the device indicating VDE compliance.

Is external filtering required on the VISO output of ADUM6202CRIZ?

Yes. The ADUM6202CRIZ requires a minimum 0.1 µF ceramic capacitor in parallel with a 10 µF bulk capacitor (e.g., tantalum or aluminum polymer) at the VISO pin, as specified in Tables 2, 6, and 10 for ripple/noise testing. Omitting this filter increases output ripple to 75 mV p-p (5 V mode) or 50 mV p-p (3.3 V mode), risking instability in noise-sensitive analog circuits like ADC references or op-amp supplies.
