ADFS5758BCPZ

Digital To Analog Converters Overview

The ADFS5758BCPZ is a single-channel, 16-bit digital-to-analog converter (DAC) featuring both current and voltage outputs on a shared terminal. It holds functional safety approval to SIL 2/SC3 for unipolar current output configurations. The device operates with supply rails ranging from −33 V to +33 V, supporting a maximum differential voltage of 60 V. Key electrical parameters include a typical settling time of 15 µs, an integrated 12-bit diagnostic ADC, and dynamic power control (DPC) via an internal buck converter. It utilizes a versatile 4-wire SPI interface capable of up to 50 MHz clock rates.

Digital To Analog Converters Feature Summary

• Functional Safety Approved: Certified to SIL 2/SC3 by TÜV Rheinland for unipolar current output applications.
• Advanced Diagnostics: Includes an independent 12-bit ADC for monitoring internal and external nodes, plus CRC and watchdog timer support.
• Dynamic Power Control: On-chip buck DC-DC converter regulates VDPC+ from 4.95 V to 27 V to minimize package power dissipation.
• Robust Protection: Features output fault protection against miswire events up to ±38 V and meets IEC 61000 EMC standards.

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 BCPZ corresponds to the LFCSP-32 package variant when sourcing. Confirm that the application design adheres to the SIL 2 certification constraints, which are valid only for unipolar current output modes. Ensure thermal management strategies account for the junction temperature limits specified in the datasheet.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high reliability and functional safety certification in industrial environments. The integrated DPC feature makes it suitable for multi-channel setups where thermal management is critical. Verify that the required output ranges (e.g., 4 mA to 20 mA or ±10 V) align with the device's programmable scaling capabilities.

Digital To Analog Converters Part Context

The ADFS5758 belongs to the AD5758 product family, designed as a successor to previous DAC generations with enhanced diagnostic features. It is part of Analog Devices' portfolio for industrial automation, often paired with companion products like the ADP1031 for isolated power solutions or AD5700 HART modems for fieldbus communication.

Digital To Analog Converters Replacement Considerations

The AD5758 is the base model for this series. Check if the standard AD5758 meets requirements if SIL 2 certification is not strictly necessary, though the ADFS5758 provides the specific safety documentation required for certified systems.
