Descripción general

Description

ADuM1250SRZ-RL7 is an Analog Devices iCoupler digital isolator that provides galvanic isolation for SPI-like (isoSPI) signals. It is a four‑channel isolator with dual supplies (VDD1 and VDD2) so you can run the two sides of the link from independent grounds. The SRZ‑RMO packaging indicates a 16‑lead RoHS, lead‑free, tape‑and‑reel version (SRZ is the package code; RL7 denotes RoHS/T&R). Typical use is to couple a host MCU to an isolated peripheral (sensors, ADC/DAC, motor drivers, etc.) across an isolation barrier, maintaining signal integrity and protecting devices in noisy or safety‑critical environments. Signals cross the barrier as SPI‑like lines (e.g., MOSI/MISO/SCK/CS) without a common ground. Benefits include noise rejection, ground‑loop elimination, and safer high‑voltage separation while preserving fast data transfer.

Features

ADUM1250SRZ-RL7 features (concise):
- 4-channel digital isolator (iCoupler) with galvanic isolation between input and output sides
- Isolation rating: 5 kV RMS per channel
- Four isolated data channels suitable for standard digital logic levels (TTL/CMOS)
- High-speed, low-power operation; data rate on the order of tens of Mbps per channel with low propagation delay
- Independent supply rails on each side; supports 3.3 V and 5 V logic
- Industrial temperature range (-40°C to +125°C)
- 16-pin SRZ lead-free, RoHS-compliant package; RL7 denotes tape-and-reel option
- Applications: SPI/I2C/SMBus interfaces, isolated sensor/peripheral connections, microcontroller-to-peripheral isolation, etc.

Package

ADUM1250SRZ-RL7 is a 16‑lead SOIC (surface-mount, gull-wing) package on a 7‑inch tape‑and‑reel (RL7).

Pinout

- Pin count: 16 pins (SOIC-16, SRZ)
- Function: 4-channel digital isolator (iCoupler) with galvanic isolation between input side (VDD1/GND1) and output side (VDD2/GND2); four unidirectional data channels (A1–A4 to B1–B4). RL7 indicates Tape & Reel packaging.
