ADUM340E0BRWZ-RL

Digital Isolators Overview

The ADUM340E0BRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler technology for high-speed signal transmission. It features four independent data channels with a maximum data rate of 150 Mbps at 5V operation. The device provides an insulation voltage of 5700 Vrms and supports a supply voltage range of 2.25V to 5.5V. Typical propagation delay is 6.2 ns, with a maximum of 10 ns. It operates within a temperature range of -40°C to +125°C and meets AEC-Q100 qualification standards. The component is housed in a 16-pin SOIC package.

Digital Isolators Feature Summary

• Integrates four independent bidirectional data channels using monolithic air-core transformer technology for robust isolation.
• Provides high common-mode transient immunity of 180 kV/µs to suppress noise in electrically noisy environments.
• Supports flexible logic levels with input/output pin compatibility across 2.25V to 5.5V supply voltages.
• Includes fault-safe output options (E0 or E1) to ensure defined states during power loss or signal failure.

Digital Isolators Applications

• Isolation for Serial Peripheral Interface (SPI) communication lines
• Signal isolation for RS-485 and Controller Area Network (CAN/CANFD) buses
• PWM controller signal isolation in industrial motor drives
• General-purpose multi-channel isolation in industrial automation systems

Digital Isolators Procurement Notes

Verify the specific suffix 'E0' indicates the fault-safe low output configuration when sourcing this part. Confirm that the SOIC-16 package matches your PCB footprint requirements. Ensure the 5700 Vrms insulation rating aligns with your system's safety isolation standards. Check for AEC-Q100 automotive qualification if the application requires automotive-grade reliability. Validate operating temperature ranges against your environmental specifications.

Digital Isolators Selection Notes

Select this component when high-speed data rates up to 150 Mbps are required alongside strong isolation capabilities. Consider the 6.2 ns typical propagation delay for timing-sensitive applications. The wide supply voltage range allows compatibility with both 3.3V and 5V logic systems. The integrated fault-safe feature simplifies design by preventing undefined outputs during startup or fault conditions. Evaluate the 180 kV/µs CMTI for environments with significant electrical noise.

Digital Isolators Part Context

This part belongs to the ADuM34xE family of quad-channel digital isolators. It shares the same core iCoupler architecture as the ADUM340E1 and ADUM341E variants. The primary distinction lies in the output configuration, where the 'E0' suffix denotes a fault-safe low state. This family is designed for applications requiring multiple isolated channels in a compact surface-mount package.

Digital Isolators Replacement Considerations

The ADUM340E1BRWZ-RL is a direct functional substitute within the same series, differing only in the fault-safe output configuration (high vs. low). Both parts share identical pinouts, packaging, and electrical characteristics except for the fail-safe state. Verify the specific fault-safe requirement before swapping between E0 and E1 variants.
