Product details
Overview
AD260AND-0 from Analog Devices is a high-speed logic isolator with integrated 1.5 W isolated power transformer, configured as five unidirectional field-side outputs (F0–F4) driven by system-side inputs (S0–S4). It delivers 20 MHz signal bandwidth, 14 ns propagation delay, ±1 ns edge symmetry, 3.5 kV rms isolation (B-grade), and operates across –25°C to +85°C for PLC analog I/O card isolation.
For engineers reviewing the AD260AND-0 datasheet, AD260AND-0 pinout, AD260AND-0 application, or AD260AND-0 equivalent, key selection criteria include its 0-input/5-output I/O configuration, transformer-driven isolated field power capability, CMV immunity of 10 kV/µs, and compatibility with HCMOS/ACMOS logic levels in safety-critical industrial control interfaces.
Technical Context
The AD260AND-0 implements Analog Devices' IsoLogic™ architecture using capacitive-coupled digital transmission across a 3.5 kV rms isolation barrier. Each of its five channels features a Schmitt-trigger input with hysteresis (0.9 V typ), transparent latch, and three-state output controlled by ENABLEFLD.
It integrates a center-tapped push-pull transformer (1 mH per half-winding, 48 turns secondary) delivering up to 1.5 W at 37 V p-p output when driven at 150–300 kHz. Continuous update circuitry ensures output validity within 12 µs after power-up reset or fault recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 3.5 kV rms (100% production tested); enables safe interface between 24 V field I/O and 5 V microcontroller systems. |
| Logic Bandwidth | 20 MHz min; supports NRZ data rates up to 40 Mbps for high-speed digital I/O port isolation. |
| Propagation Delay | 14 ns typ; ensures nanosecond-level timing integrity for PWM signal isolation in motor drives. |
| Edge Symmetry Error | ±1 ns max (tPHL vs tPLH); preserves duty cycle fidelity critical for time-based control signals. |
| Transformer Output | 37 V p-p at 5 V drive; supplies regulated ±5 V, +15 V, or 24 V loop power without external isolation DC/DC. |
| CMV Immunity | 10 kV/µs min; prevents false triggering during fast transients in noisy industrial environments like IGBT gate drive circuits. |
| Supply Voltage Range | 4.5 V to 5.5 V dc (system & field sides); compatible with standard 5 V logic rails and tolerant of rail droop. |
| Operating Temperature | –25°C to +85°C; rated for continuous operation in industrial PLC backplanes and DCS modules. |
Pinout & Package
AD260AND-0 is housed in a 22-lead plastic DIP (ND-22) package with >18 mm creepage distance between system and field sides, supporting 750 V mains isolation per IEC60950.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–5 (S0–S4) | System-side digital inputs | Drive five isolated field outputs; must be tied high/low (not floating) per HCMOS input requirements. |
| 6 (ENABLESYS) | System output enable | Three-states all system-side outputs; used for multiplexing multiple AD260AND-0 devices on shared buses. |
| 7 (+5 V dcSYS) | System power supply | Primary 5 V rail for system-side logic and transformer driver; requires local 0.01 µF bypass. |
| 8 (5 V RTNSYS) | System ground reference | Return path for system-side supply and logic; separate from field ground to maintain isolation integrity. |
| 15 (5 V RTNFLD) | Field ground reference | Return for field-side outputs and transformer secondary; galvanically isolated from system ground. |
| 16 (+5 V dcFLD) | Field power supply | Supplies field-side output buffers; derived from transformer or external source; bypass required. |
| 17 (ENABLEFLD) | Field output enable | Three-states all five F0–F4 outputs; enables safe power-up sequencing with pull-up/down resistors. |
| 18–22 (F0–F4) | Field-side digital outputs | Five unidirectional CMOS-compatible outputs; each capable of ±25 mA drive into field loads. |
Key Features
| Feature | Design Value |
|---|---|
| Five-channel logic isolation | Replaces up to five optocouplers with matched timing, eliminating channel-to-channel skew and aging drift. |
| Integrated 1.5 W transformer | Eliminates need for external isolated DC/DC; supports 24 V loop power or dual ±5 V regulation directly from 5 V system rail. |
| Continuous output update | Guarantees valid F0–F4 states within 12 µs after power-up or fault, even with no input transitions. |
| 10 kV/µs CMV immunity | Prevents spurious output toggling during fast transients common in motor drive and relay switching noise environments. |
| PIN-compatible I/O variants | Shares identical ND-22 footprint with AD260AND-1 through AD260AND-5, enabling design reuse across input/output ratio changes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed logic isolation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM1401ARWZ | Quad-channel, 100 Mbps, 2.5 kV rms, no integrated power; requires external isolated DC/DC. | Lacks transformer-based field power; suitable only where isolated supply already exists. | Choose when board space allows discrete DC/DC and only four channels are needed. |
| SI8650BD-B-IS | Five-channel, 150 Mbps, 5 kV rms, no integrated power; uses capacitive isolation, higher CMTI (75 kV/µs). | No transformer output; optimized for ultra-high-noise immunity but adds external power complexity. | Prefer for extreme EMI environments where transformer size/EMI is unacceptable. |
Compared with AD260AND-0, ADUM1401ARWZ offers higher data rate but lacks integrated power and channel count, while SI8650BD-B-IS provides superior transient immunity and isolation voltage but requires external isolated supply - making AD260AND-0 uniquely suited for self-powered field-side subsystems in PLC and motor control.

FAQ
What is the isolation test voltage rating for AD260AND-0?
The AD260AND-0 is rated for 3.5 kV rms isolation test voltage (100% production tested), meeting UL1950, IEC950, and EN60950 safety standards. This rating applies to the system-to-field barrier and supports operation at 1.25 kV rms working voltage in industrial environments.
Can AD260AND-0 generate isolated field power without external components?
Yes - AD260AND-0 integrates a center-tapped transformer capable of delivering up to 1.5 W of isolated power. When driven with a 5 V push-pull signal at 150–300 kHz on the system side, it produces 37 V p-p on the secondary, which can be rectified and regulated to ±5 V, +15 V, or 24 V for field-side circuitry.
How does AD260AND-0 handle power-up initialization?
AD260AND-0 enters a power-up reset mode for ~30 µs after either supply crosses 3.3 V, disabling all outputs. Its continuous update circuit then ensures all five F0–F4 outputs reflect valid input states within 12 µs after reset completion - critical for deterministic startup in safety-critical systems.
What is the maximum data rate supported by AD260AND-0?
AD260AND-0 supports a minimum logic signal bandwidth of 20 MHz and 40 Mbps NRZ data rate. Its 14 ns propagation delay and ±1 ns edge symmetry error enable accurate transmission of high-frequency PWM and clock signals without duty cycle distortion.
Does AD260AND-0 require external bypass capacitors?
Yes - Analog Devices specifies 0.01 µF ceramic capacitors placed near pins 7 (+5 V dcSYS) and 16 (+5 V dcFLD), plus internal 0.05 µF bypassing. These are mandatory for stable operation, EMI suppression, and achieving CE certification in end equipment per the EMC directive.
