Product details
Overview
ADUM5411BRSZ-RL7 from Analog Devices is a quad-channel digital isolator with integrated isoPower® DC-to-DC converter, providing 3.3 V isolated output at up to 20 mA (66 mW) and 150 Mbps signal isolation per channel. It features 24-lead SSOP packaging, 5.3 mm minimum creepage, and operates across −40°C to +105°C for industrial PLCs and isolated sensor interfaces.
For engineers reviewing the ADUM5411BRSZ-RL7 datasheet, ADUM5411BRSZ-RL7 pinout, ADUM5411BRSZ-RL7 application, or ADUM5411BRSZ-RL7 equivalent, this device delivers verified reinforced insulation (VIORM = 573 V peak), high CMTI (100 kV/µs), and configurable output voltage via external resistor network - critical for safety-critical isolated power and data transmission in compact designs.
Technical Context
The ADUM5411BRSZ-RL7 implements iCoupler® chip-scale transformer technology for both signal isolation and isolated DC-DC conversion, eliminating external isolated power supplies. Its architecture supports independent input/output voltage domains (VDD1 = 3.3 V/5 V, VISO = 3.3 V/5 V), with internal PWM control (600 kHz) and 125 MHz oscillator frequency.
It provides asymmetric channel directionality: three input-to-output channels (I/O1A–I/O1C) and one output-to-input channel (I/O1D), enabling bidirectional communication in master-slave configurations. Propagation delay skew is ≤7.5 ns between any two channels, and pulse width distortion remains ≤3.0 ns across temperature and supply variations.

Pinout & Package
ADUM5411BRSZ-RL7 uses a 24-lead SSOP package (7.6 mm × 12.8 mm, 0.635 mm pitch) with exposed thermal pad. Pin functions are defined per Table 2 of the datasheet, with dedicated VDD1, VDD2, GND1, GND2, VISO, GNDISO, and four bidirectional data channels.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 7, 8, 17, 18, 23, 24 | GND1 / GND2 / GNDISO | Separate ground domains: GND1 (input side), GND2 (output side), GNDISO (isolated DC-DC return) |
| 3–6 | I/O1A–I/O1D | Input/output data channels: I/O1A–I/O1C = input-to-output; I/O1D = output-to-input (per ADuM5411 configuration) |
| 9–12, 19–22 | VOA–VOD / VIA–VID | Output-side (VOx) and input-side (VIx) signal terminals - mapped to specific channel direction per ordering variant |
| 13, 14 | VDD1 / VDD2 | Primary-side (3.3 V/5 V) and secondary-side (3.3 V) logic supply pins - decoupling required per datasheet layout guidelines |
| 15, 16 | VISO / GNDISO | Regulated isolated output (3.3 V) and its return - connects to external capacitor network (0.1 µF || 10 µF) for ripple suppression |
| 17 | VSEL | Voltage select pin - sets VISO via external R1/R2 divider (10 kΩ / 16.9 kΩ for 3.3 V output) |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel isolated DC-DC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM5410BRSZ-RL7 | Four forward-direction channels (I/O1A–I/O1D all input-to-output); no reverse channel | Suitable for unidirectional data flow only (e.g., sensor readout without command echo) | Select when full-duplex operation is unnecessary and lower quiescent current in logic-0 state is prioritized |
| ADUM5412BRSZ-RL7 | Two forward + two reverse channels (I/O1C/I/O1D output-to-input); higher IDD1(Q) at logic-1 | Better suited for bidirectional protocols requiring equal channel flexibility (e.g., I²C with clock stretching) | Choose when symmetric bidirectional capability across all four channels is required, accepting slightly higher power consumption |
Compared with ADUM5411BRSZ-RL7, ADUM5410BRSZ-RL7 offers lower static power in receive-only use cases, while ADUM5412BRSZ-RL7 provides balanced bidirectionality at the cost of increased IDD1(Q) - making ADUM5411BRSZ-RL7 optimal for asymmetric full-duplex systems like SPI master-slave with status feedback.

FAQ
What is the maximum isolated output power of the ADUM5411BRSZ-RL7?
The ADUM5411BRSZ-RL7 delivers up to 66 mW at 3.3 V (20 mA) when configured for 3.3 V primary and secondary operation. This is confirmed in Table 7 of the datasheet under "3.3 V Primary Input Supply / 3.3 V Secondary Isolated Supply" conditions. The output is regulated and supports typical loads such as isolated ADCs or level translators without external regulation.
Does the ADUM5411BRSZ-RL7 support 5 V isolated output?
No - the ADUM5411BRSZ-RL7 is factory-configured for 3.3 V isolated output. While the ADuM541x family includes variants supporting 5 V output (e.g., ADUM5410/5412 with different VSEL networks), the ADUM5411BRSZ-RL7 datasheet specifies R1 = 10 kΩ / R2 = 16.9 kΩ for 3.3 V setpoint, and no 5 V VISO configuration is validated for this specific part number.
How is channel directionality defined in the ADUM5411BRSZ-RL7?
The ADUM5411BRSZ-RL7 has three input-to-output channels (I/O1A, I/O1B, I/O1C) and one output-to-input channel (I/O1D), as shown in Table 2 of the datasheet. This asymmetric configuration supports master-slave protocols where three signals flow from controller to peripheral and one returns status or acknowledgment - ideal for SPI or custom command-response interfaces.
What safety certifications apply to the ADUM5411BRSZ-RL7?
The ADUM5411BRSZ-RL7 is certified to UL 1577 (2500 V rms, 1 min), DIN EN IEC 60747-17 (VDE 0884-17, VIORM = 573 V peak), IEC/CSA 60601-1 (1 MOPP), and IEC/CSA 62368-1. These are listed in Table 22 of the datasheet and verified per production lot testing - not derived from family-level claims.
Can the ADUM5411BRSZ-RL7 operate with 1.8 V logic supplies?
Yes - the ADUM5411BRSZ-RL7 supports 1.8 V operation on both VDD1 and VDD2 sides, as specified in Table 19 and Table 20 of the datasheet. At 1.8 V, it maintains 150 Mbps data rate, 100 kV/µs CMTI, and full functionality, though isolated output remains fixed at 3.3 V (VISO) and requires external regulation if powering 1.8 V loads.
