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 with analog supplies ranging from -33 V to +33 V on AVSS/AVDD1 and supports logic voltages 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 against miswire events up to ±38 V. It utilizes a versatile 4-wire serial interface compatible with SPI, QSPI, MICROWIRE, DSP, and microcontroller standards, operating at clock rates up to 50 MHz.
Feature Summary
- 16-bit resolution with guaranteed monotonicity and integrated on-chip reference
- Dynamic Power Control (DPC) using internal buck converters for thermal management
- HART network connectivity via the CHART pin coupled on the current output
- Advanced diagnostics including a 12-bit ADC with two external input pins
Applications
- Process control systems
- Actuator control loops
- Programmable logic controller (PLC) modules
- Distributed control system (DCS) channels
- Channel-isolated analog outputs
Procurement Notes
Verify the specific suffix RL7 indicates reel packaging when sourcing components. Confirm that the B grade meets the required temperature range specifications of -40°C to +115°C for the intended industrial application environment. Ensure compatibility with the 40-lead LFCSP package dimensions during PCB layout.
Selection Notes
Select this component for applications requiring high precision in harsh industrial environments due to its wide operating temperature range and robust architecture. Consider the DPC feature if thermal management within dense module housings is critical. Verify that the supply voltage margins accommodate the maximum 60 V differential between AVDD1 and AVSS.
Part Context
This part belongs to the AD5753 family of single-channel DACs designed for industrial process control. It serves as a companion to devices like the AD5758 and AD5755-1. Evaluation is supported by the EVAL-AD5753SDZ board, which facilitates testing of the DAC's diagnostic and power control features in development stages.
Replacement Considerations
The AD5758 is listed as a companion product within the same functional family. Users should verify pinout compatibility and register map differences before substituting.
