Analog Devices Inc. ADUM5210ARSZ

Overview

ADuM5210ARSZ 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 output (up to 150 mW) in a single 20-lead SSOP package. It delivers two unidirectional signal channels supporting up to 100 Mbps NRZ data rate, 25 kV/µs common-mode transient immunity, and operates across −40°C to +105°C for industrial PLC and isolated sensor interface applications.

For engineers reviewing the ADuM5210ARSZ datasheet, ADuM5210ARSZ pinout, ADuM5210ARSZ application, or ADuM5210ARSZ equivalent, this page provides verified specifications, validated pin functions, safety-certified insulation parameters (UL 1577, VDE 0884-17, VIORM = 600 V peak), and real-world design context for isolated power and signal transfer in RS-232 transceivers and gate drive bias circuits.

Technical Context

The ADuM5210ARSZ uses iCoupler® chip-scale transformer technology for both signal isolation and magnetic power transfer, eliminating external isolated DC-DC converters. Its isoPower section operates at 125 MHz switching frequency and 600 kHz PWM, with soft-start and thermal shutdown (154°C) for robust operation.

Signal channels feature independent input (VDD1) and output (VDD2) supplies, configurable VISO output voltage via VSEL resistor network, and support for SPI clock rates up to 15 MHz. Propagation delay skew is ≤12 ns (C grade), pulse width distortion ≤2 ns, and refresh rate is 1.6 µs to maintain DC correctness.

FAQ

What is the maximum isolated output power of the ADuM5210ARSZ?

The ADuM5210ARSZ delivers up to 150 mW of isolated output power at 5 V (30 mA), or 66 mW at 3.3 V (20 mA), depending on input/output voltage configuration. This power is sourced from the VISO pin and is sufficient to supply downstream logic such as isolated ADCs, transceivers, or microcontroller I/O. The actual usable power depends on thermal conditions and ambient temperature - derating applies above 85°C per Table 18.

Can the ADuM5210ARSZ support both 3.3 V and 5 V isolated output voltages?

Yes, the ADuM5210ARSZ supports programmable VISO output of either 3.3 V or 5.0 V via the VSEL pin and an external resistor divider. When R1 = 10 kΩ and R2 = 16.9 kΩ between VISO and GNDISO, VISO is regulated to 3.3 V; with R2 = 30.9 kΩ, it is regulated to 5.0 V. The VSEL network must match the internal 1.25 V reference, and output remains stable across load (1.3–3% load regulation) and line (20 mV/V) variations.

What safety certifications does the ADuM5210ARSZ hold?

The ADuM5210ARSZ is certified to UL 1577 (2500 V rms, 1 min), DIN EN IEC 60747-17 (VDE 0884-17, VIORM = 600 V peak), IEC/CSA 62368-1, IEC/CSA 61010-1, and CQC GB 4943.1. It provides reinforced insulation with 5.3 mm creepage/clearance and meets Pollution Degree 2 requirements. These certifications validate its suitability for industrial, medical, and test equipment where functional safety and regulatory compliance are mandatory.

How does the PDIS pin function in the ADuM5210ARSZ?

The PDIS (Power Disable) pin on the ADuM5210ARSZ is an active-low control input that enables or disables the internal isoPower DC-DC converter. When pulled low (≤0.8 V), the converter operates normally; when pulled high (≥2.0 V), it enters low-power standby mode, reducing quiescent current from ~104 mA (full load) to ~3.2 mA (no VISO load). This feature allows dynamic power management in battery-backed or energy-sensitive systems without disrupting signal isolation.

What is the propagation delay and skew specification for the ADuM5210ARSZ at 100 Mbps?

At 100 Mbps (C grade), the ADuM5210ARSZ exhibits typical propagation delay of 20 ns (tPHL/tPLH), pulse width distortion ≤2 ns, and channel-to-channel propagation delay skew ≤12 ns. These values are measured under standard conditions (CL = 15 pF, CMOS levels) and ensure tight timing alignment for synchronous protocols like SPI or parallel control signals. Skew remains stable across temperature (−40°C to +105°C) and supply voltage (3.135–5.5 V).
