ADM2914-1SRQZEP-R7

Supervisors Overview

The ADM2914-1SRQZEP-R7 is a robust, isolated RS-485 transceiver manufactured by Analog Devices Inc. It features a 5 kVrms isolation barrier and supports data rates up to 20 Mbps. The device operates within an extended temperature range of -55°C to +125°C and includes comprehensive protection against short circuits and electrostatic discharge. Packaged in a small SOIC-16 form factor, it integrates high-level EMC immunity suitable for harsh industrial environments.

Supervisors Feature Summary

• Provides 5 kVrms reinforced isolation between signal and power domains
• Integrates full 42 V protection on bus pins for fault tolerance
• Delivers Level 4 EMI immunity per IEC 61000-4 standards
• Supports half-duplex communication with fail-safe receiver logic

Supervisors Applications

• Industrial automation control networks
• Factory floor sensor interfaces
• Process control instrumentation
• Energy metering systems

Supervisors Procurement Notes

Verify the specific suffix 'EP' indicates enhanced performance or military-grade screening requirements. Confirm package dimensions match the SOIC-16 footprint. Ensure supply chain sources provide valid traceability documentation for qualified components.

Supervisors Selection Notes

Select this component when high voltage isolation and extreme temperature stability are required. Compare input/output voltage levels against system logic. Evaluate thermal dissipation capabilities within the enclosed housing design constraints.

Supervisors Part Context

This part belongs to the ADM291x family of isolated RS-485/RS-422 transceivers. It shares functional similarities with standard ADM2914 variants but includes specialized qualification markings. The series targets applications demanding reliable communication under severe electrical noise conditions.

Supervisors Replacement Considerations

Direct substitutes include ADM2914-1SRQZ-R7 for non-enhanced versions. Verify pin compatibility before swapping with ADM2916 or ADM2917 variants.
