AD5758BCPZ-REEL

Overview

The AD5758BCPZ-REEL is a single-channel, 16-bit digital-to-analog converter (DAC) featuring both current and voltage outputs on a shared terminal. It operates with a supply range of -33 V to +33 V and includes an integrated buck DC-DC converter for dynamic power control (DPC). The device supports HART connectivity via the CHART pin and utilizes a versatile 4-wire SPI interface compatible with standard protocols up to 50 MHz. Key specifications include a settling time of 15 µs, ±1 LSB DNL, and an integrated 12-bit diagnostic ADC. It is housed in a 32-lead, 5 mm × 5 mm LFCSP package.

Feature Summary

• Integrated Dynamic Power Control (DPC) using a buck DC-DC converter to minimize thermal dissipation.
• HART signal coupling capability enabled by the dedicated CHART pin.
• Advanced diagnostics including a 12-bit internal ADC and output fault protection.
• Robust EMC performance meeting IEC 61000-4 standards for conducted immunity, radiated immunity, ESD, EFT, and surge.

Applications

• Process control systems
• Actuator control loops
• Programmable logic controllers (PLC)
• Distributed control systems (DCS)
• Channel-isolated analog output modules

Procurement Notes

Verify that the REEL suffix corresponds to tape-and-reel packaging suitable for automated assembly. Confirm the specific revision level against the latest Analog Devices documentation to ensure compatibility with required diagnostic features and EMC compliance levels.

Selection Notes

Select this component when high accuracy (16-bit) and robust fault protection are required in space-constrained designs. The integrated DPC makes it suitable for applications where thermal management is critical. Ensure the system power supply allows for the maximum 60 V differential between AVDD1 and AVSS.

Part Context

This part belongs to the AD5758 family of industrial DACs. It serves as a high-integration solution combining the DAC core, reference, drivers, and power management in a small footprint. It is often paired with companion products like the ADP1031 PMU for isolated multi-channel modules.

Replacement Considerations

The ADFS5758BCPZ is a Functional Safety certified version of the AD5758. Verify if safety certification is required; otherwise, the standard AD5758 variants may be considered. Other family members like the AD5753 offer similar functionality but may lack specific diagnostic or HART features.
