ADFS5758BCPZ-RL7

Digital To Analog Converters Overview

The ADFS5758BCPZ-RL7 is a single-channel, 16-bit digital-to-analog converter (DAC) featuring current and voltage outputs on a shared terminal. It holds functional safety approval to SIL 2/SC3 for unipolar current output configurations. The device supports multiple output ranges, including 0 mA to 24 mA and ±10 V, with an integrated 12-bit ADC for independent monitoring. It operates within a temperature range of −40°C to +105°C and utilizes a 4-wire SPI interface compatible with standard DSP and microcontroller protocols.

Digital To Analog Converters Feature Summary

• Functional safety approved to SIL 2/SC3 by TÜV Rheinland for unipolar current output applications.
• Integrated 12-bit diagnostic ADC enables independent validation of internal and external nodes.
• Dynamic Power Control (DPC) using an on-chip buck DC-DC converter minimizes power dissipation.
• Robust EMC performance compliant with IEC 61000-4 standards for conducted immunity, radiated immunity, ESD, and surge.

Digital To Analog Converters Applications

• Process control systems
• Actuator control loops
• Programmable logic controllers (PLC)
• Distributed control systems (DCS)
• HART network connectivity

Digital To Analog Converters Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing from distributors. Confirm that the Functional Safety Certificate matches the required SIL level for the intended application. Ensure the design accounts for the LFCSP-32 package thermal requirements to maintain junction temperatures below 125°C during operation.

Digital To Analog Converters Selection Notes

Select this component for applications requiring a single-channel DAC with certified functional safety capabilities. The ADFS5758 is suitable where high accuracy (16-bit resolution) and robust fault protection are necessary. Consider the companion ADP1031 if channel isolation is required for multi-channel setups.

Digital To Analog Converters Part Context

The ADFS5758 belongs to the Analog Devices industrial DAC family, designed as a successor to predecessors like the AD5758. It integrates advanced diagnostics and thermal management features not present in earlier models. The device is part of a broader ecosystem including HART modems like the AD5700 and digital isolators such as the ADuM142D.

Digital To Analog Converters Replacement Considerations

The AD5758 serves as the non-functional-safety variant of this component. For system upgrades or replacements, verify that the SIL certification requirements can be met by the ADFS5758 or if the standard AD5758 suffices for non-safety-critical paths.
