概述

Description

ADUM7641CRQZ is a four-channel digital isolator from Analog Devices (iCoupler technology). It provides galvanic isolation between two separate sides of a circuit, allowing digital signals to pass across the isolation barrier without a direct electrical connection. Each channel transfers a signal from one side to the other, using separate supply rails on each side (VDD1 and VDD2).
Key points:
- 4 isolated data channels in an 8‑pin package (CRQZ is the RoHS 8‑lead SOIC variant).
- Isolation typically rated around several kilovolts (voltage across barrier) with no optocouplers.
- Compatible with common logic levels; both sides powered independently (typical 3–5.5 V ranges).
- Low power, fast edges, suitable for industrial and automotive environments.
Typical uses: isolating SPI/I2C/UART lines, GPIOs, and other digital signals to protect low-voltage controllers from high-voltage/noisy domains.
Note: consult the datasheet for exact pinout, channel directions, propagation delay, and device ratings.

Features

ADUM7641CRQZ is a four‑channel iCoupler digital isolator. Key features:
- Four independent, unidirectional data channels (isolated between input and output sides)
- Reinforced isolation rating at 5 kV rms (input/output isolation)
- Dual supplies on each side: VDD1 and VDD2 with compatible 3.3/5.0 V operation
- High-speed data capability suitable for SPI/I2C and general digital buses
- Fast propagation with low jitter and low power per channel
- High common‑mode transient immunity and robust ESD protection
- RoHS-compliant, 16‑lead package (CRQZ), available for industrial temperature range (-40°C to +125°C)
Recommended use: isolate microcontroller interfaces from noisy/high-voltage sections, e.g., SPI peripherals and control signals.

Package

The ADUM7641CRQZ comes in a 20‑lead surface‑mount package, specifically a 20‑lead LQFP (5x5 mm) RoHS‑compliant variant.

Pinout

- Pin count: 16 pins (16‑lead package, e.g., SOIC).
- Function: ADUM7641CRQZ is a quad-channel digital isolator (iCoupler). It provides galvanic isolation between the input side (VDD1/VSS1) and the output side (VDD2/VSS2) with four isolated data channels, typically used to isolate interfaces such as SPI/UART.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI).
- What kind of company: A global American semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits (e.g., data converters, op-amps, sensors, power management, and isolation devices like iCoupler).

Application

ADuM7641CRQZ is a digital isolator. Typical application areas include galvanic isolation of microcontrollers/DSPs in noisy/high-voltage environments: industrial automation/control, motor drives and power electronics, energy meters/smart grid, instrumentation and data acquisition, automotive and medical electronics. It enables isolated interfaces (SPI, I2C, UART) and protects low-voltage circuitry from transients.

Equivalent

Possible equivalents (4-channel digital isolators with similar specs to ADuM7641CRQZ):
- Texas Instruments ISO7641 family (e.g., ISO7641, ISO7642)
- Broadcom/Avago HCPL-7840 and HCPL-7841
- NVE IL600/IL700 series digital isolators
All offer similar isolation (about 5 kV rms reinforced), 3.3–5 V operation, and multi-channel isolation. Check pinout and package compatibility for your design.
