AD5753BCPZ

Overview

The AD5753BCPZ-RL7 is a single-channel, 16-bit digital-to-analog converter (DAC) featuring current and voltage outputs with dynamic power control (DPC) and HART connectivity. It operates on analog supplies ranging from -33 V to +33 V and a logic supply of 1.71 V to 5.5 V. The device integrates an on-chip reference, a 12-bit diagnostic ADC, and robust output fault protection. Key electrical parameters include a settling time of 15 µs in programmable power control mode, ±0.006% FSR integral nonlinearity, and ±1 LSB differential nonlinearity. It utilizes a versatile 4-wire serial interface compatible with SPI, QSPI, Microwire, DSP, and microcontroller standards.

Feature Summary

• Integrated Dynamic Power Control (DPC) using buck dc-to-dc converters for thermal management
• HART network connectivity via the CHART pin
• Advanced diagnostics including a 12-bit ADC and two external input pins
• Output fault protection against miswire events up to ±38 V

Applications

• Process control systems
• Actuator control
• Programmable logic controller (PLC) and distributed control systems (DCS)
• Channel isolated analog outputs
• HART network connectivity

Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the Reel packaging format when sourcing components. Confirm that the BC grade meets the required temperature range and accuracy specifications for the intended application environment. Ensure compatibility with the EVAL-AD5753SDZ evaluation board for initial system validation.

Selection Notes

Select this component for applications requiring high precision (16-bit resolution) and robust fault tolerance in industrial environments. Consider the DPC feature if thermal management within small module housings is critical. Verify that the available current ranges (e.g., 4 mA to 20 mA, ±20 mA) and voltage ranges (e.g., 0 V to 10 V, ±10 V) align with the load requirements.

Part Context

The AD5753 belongs to Analog Devices' family of advanced DACs designed for industrial process control. It serves as a companion to products like the AD5758 and AD5755-1. The device is supported by the EVAL-AD5753SDZ evaluation board and can be paired with HART modems such as the AD5700 for complete communication solutions.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Designers should consult the manufacturer's documentation for potential cross-references or updated revisions.
