Analog Devices Inc. ADUM5410BRSZ

Overview

ADUM5410BRSZ from Analog Devices is a quad-channel digital isolator with integrated isoPower® isolated DC-to-DC converter, delivering up to 150 mW output power at 5 V/5 V operation, supporting data rates up to 150 Mbps per channel, and featuring 24-lead SSOP package with 5.3 mm minimum creepage for industrial PLC and isolated sensor interface applications.

For engineers reviewing the ADUM5410BRSZ datasheet, ADUM5410BRSZ pinout, ADUM5410BRSZ application, or ADUM5410BRSZ equivalent, this page provides verified functional specifications, safety-certified isolation parameters, confirmed pin assignments for I/O1A–I/O1D and I/O2A–I/O2D, and real-world design implications of its 100 kV/µs CMTI and 2500 V_rms reinforced insulation.

Technical Context

The ADUM5410BRSZ implements iCoupler® chip-scale transformer technology for both signal isolation and magnetic DC-DC conversion, eliminating external isolated power supplies. Its four unidirectional channels (A/B/C/D on side 1, A/B/C/D on side 2) are fixed in input-output direction per variant - ADUM5410 has all four channels input-side-to-output-side (VIA/VIB/VIC/VID → VOA/VOB/VOC/VOD).

It supports multiple input/output voltage combinations: 5 V primary / 5 V isolated (150 mW), 5 V / 3.3 V (100 mW), or 3.3 V / 3.3 V (66 mW), with regulated VISO set via external resistor network (R1 = 10 kΩ, R2 = 30.9 kΩ for 5 V output). Thermal shutdown activates at 154°C with 10°C hysteresis.

Key Specifications

Pinout & Package

FAQ

What is the maximum output power of the ADUM5410BRSZ's integrated DC-DC converter?

The ADUM5410BRSZ delivers up to 150 mW of isolated output power when configured for 5 V input and 5 V output (VDD1 = VISO = 5 V). At 5 V input / 3.3 V output, it provides 100 mW; at 3.3 V / 3.3 V, it supplies 66 mW. This power is sufficient to operate small isolated loads such as microcontroller I/O banks, ADC references, or gate driver bias circuits without external DC-DC stages. The ADUM5410BRSZ's efficiency reaches 29% at full 5 V load.

Does the ADUM5410BRSZ support bidirectional communication across its isolation barrier?

No - the ADUM5410BRSZ is strictly unidirectional: all four channels transmit from side 1 (pins 3–6: VIA–VID) to side 2 (pins 17–20: VOA–VOD). Unlike the ADUM5411BRSZ or ADUM5412BRSZ variants, it does not support reverse-direction signaling. This architecture eliminates contention risks and simplifies timing analysis in master-peripheral topologies. For bidirectional needs, ADUM5411BRSZ is the designated alternative.

What safety certifications apply to the ADUM5410BRSZ?

The ADUM5410BRSZ holds UL 1577 (2500 V_rms, 1 min), IEC/CSA 62368-1, IEC/CSA 60601-1 (1 MOPP), IEC/CSA 61010-1, CQC GB 4943.1, and DIN EN IEC 60747-17 (VDE 0884-17) certifications. Its VIORM = 573 V_peak qualifies it for reinforced insulation in medical and industrial safety-critical applications - a key differentiator versus alternatives lacking VDE 0884-17 approval.

How does the ADUM5410BRSZ achieve high common-mode transient immunity (CMTI)?

The ADUM5410BRSZ achieves 100 kV/µs CMTI through iCoupler® chip-scale transformer isolation, which inherently rejects fast common-mode transients by coupling only differential signal energy. Its 2.2 pF input-to-output capacitance minimizes capacitive coupling of noise, and the transformer-based architecture avoids the slow response and saturation issues of optocouplers or capacitive isolators under high dv/dt stress - critical in motor drives and switch-mode power supplies.

Can the ADUM5410BRSZ operate with 1.8 V or 2.5 V logic supplies?

Yes - the ADUM5410BRSZ supports 1.8 V and 2.5 V operation on both sides (VDD1 and VDD2) for digital isolation channels only. However, the integrated DC-DC converter requires ≥3.0 V on VDD1 and produces VISO only in 3.3 V or 5 V configurations (set via external resistors). So while logic I/O can run at 1.8 V/2.5 V, the isolated power rail remains fixed at 3.3 V or 5 V - enabling mixed-voltage system interfacing without level shifters.
