ADUM1250SRZ-RL7

ADuM1250SRZ-RL7 is Analog Devices’ iCoupler digital isolator: a four-channel (quad) digital isolator that provides galvanic isolation between two sides of a system. It is used to transfer multiple digital signals (e.g., SPI, I2C, UART) across an isolation barrier while keeping the two sides powered independently.
Key points:
- Four independent data channels with isolation between primary and secondary sides
- iCoupler technology for high noise immunity, fast edges, and low power
- Dual supplies required on each side (VDD1 and VDD2) with a high isolation rating (typical 5 kV RMS)
- SRZ indicates the 16-lead SOIC package; RL7 denotes tape-and-reel packaging
Typical applications: microcontroller/peripheral isolation, industrial automation, motor drives, medical devices, and any system needing safe, isolated digital signaling.
In short: a compact, high-speed, four-channel digital isolator that safely bridges two circuits while minimizing ground-loop issues and protecting sensitive logic.

Direct equivalents are other 4‑channel digital isolators with similar specs. Examples:
- ADI: ADuM1250/1251/1252/1253 (same family)
- TI: ISO7741/ISO7742 (4-channel digital isolators)
- Silicon Labs: Si86xx/Si862x iCoupler quad-channel isolators
Note: verify speed, 3.3V/5V supply, package/pinout, and isolation rating; RL7 is reel packaging.

ADuM1250SRZ-RL7 features (concise):
- 4-channel iCoupler digital isolator
- Isolated SPI interface (SCLK, MOSI, MISO, CS) across the barrier
- Dual-supply isolation: VDD1 (input side) and VDD2 (output side)
- Isolation rating: 2.5 kVrms (IEC) between sides
- Data rate up to ~5 Mbps
- Low propagation delay with good common-mode transient immunity
- Wide operating temperature: -40°C to +125°C
- Packaging: 8-pin SRZ (SOIC) with RoHS compliance; reel packaging RL7
- Suitable for 3.3/5V systems; support for dual-voltage operation across the barrier
- No opto components; compact, robust, low power

- Pin count: 16 pins (SOIC-16, RoHS).
- Function: ADuM1250SRZ-RL7 is a four-channel digital isolator (iCoupler) with separate VDD1 and VDD2 supplies, providing galvanic isolation for four data lines between the primary and secondary sides (e.g., for isolated SPI/I2C interfaces).

Analog Devices, Inc. (ADI). It is an American multinational semiconductor company that designs, manufactures, and markets analog, mixed-signal, and DSP integrated circuits.

ADuM1250SRZ-RL7 is a digital isolator used for galvanically isolating fast digital signals. Common application areas include:
- Isolated MCU-to-peripheral interfaces (SPI, I2C, UART)
- Isolated sensor and actuator networks in industrial automation
- Isolated data paths in motor drives, power electronics, and inverters
- Data acquisition and instrumentation to prevent ground loops
- Safety-critical or noise-sensitive electronics in medical/industrial equipment requiring isolation
In short: any system needing high-speed, safe, galvanic isolation Between a host processor and remote digital peripherals.

ADUM1250SRZ-RL7 is in an 8‑pin SOIC (small‑outline) package, RoHS compliant (lead-free).
