ADUM6401CRIZ-RL

Overview

The ADUM6401CRIZ-RL is a quad-channel digital isolator from Analog Devices, featuring an integrated isoPower isolated DC-to-DC converter. It provides signal isolation across four channels with a data rate of 25 Mb/s and a propagation delay of 60 ns. The device supports a supply voltage range of 3 V to 5.5 V and offers an insulation voltage of 5000 Vrms. It operates within a temperature range of -40°C to +105°C and is housed in a 16-lead SOIC package.

Feature Summary

• Integrates an isolated DC-to-DC converter providing up to 400 mW of regulated power
• Utilizes iCoupler magnetic coupling technology for high common-mode transient immunity
• Features Schmitt-triggered inputs for noise rejection and signal integrity

Applications

• RS-232, RS-422, and RS-485 transceiver isolation
• Medical equipment isolation barriers
• AC/DC power supply start-up bias and gate drive circuits
• Isolated sensor interfaces

Procurement Notes

Verify the specific suffix 'CRIZ' against the official Analog Devices datasheet to confirm the RI-16-1 package variant with enhanced creepage distance. Confirm RoHS compliance status and lead-free specifications directly with the manufacturer or authorized distributors, as packaging and regulatory details may vary by production batch.

Selection Notes

Select this component when a compact solution requires both signal isolation and isolated power generation in a single package. It is suitable for designs needing 25 Mbps data rates and high common-mode transient immunity exceeding 25 kV/µs. Ensure the application fits within the 400 mW power budget provided by the internal converter.

Part Context

This part belongs to the ADuM640x family of quad-channel digital isolators. These devices are designed to eliminate the need for separate isolated power supplies in low-power applications. The family utilizes proprietary iCoupler technology to provide robust isolation performance in a small form factor.

Replacement Considerations

Check the ADUM6400, ADUM6402, ADUM6403, and ADUM6404 series for alternative channel configurations or directionality options. Verify pin compatibility and power output requirements before substituting with other members of the ADuM640x family.
