Solution ADI’s highly integrated AD5755 data converter is a complete multichannel control integrated circuit (IC) that incorporates four precision 16-bit DACs with programmable voltage or 4 mA to 20 mA output drivers, along with dynamic power control. The dynamic power control feature works by continually sensing the load impedance and delivering only the required power to the load, thus minimizing power loss in the rest of the system. This feature reduces self-heating and temperature elevation in dense, multichannel system racks. The unparalleled combination of features and performance found in the AD5755 enables up to 4× more terminals at twice the performance in a single analog I/O module. Compared to other driver technologies available today, the AD5755 lowers power consumption by up to 80% and net thermal rise (silicon temperature minus ambient temperature) by 75%. The 16-bit AD5755 offers a full-channel specification with a maximum total unadjusted error of 0.05% and a relative accuracy of ±0.003% max and does not require system calibration, which shortens development time and reduces system maintenance costs. In addition, the single chip architecture combines multiple converter, power management, linear, and other functions, increasing mean time-to-failure (MTTF) and improving reliability. Also included are various diagnostics for real-time fault analysis, including communication, connection, and interface alerts, which simplify the design task and boost operational up-time. The AD5755 supports standard industrial voltage and current output ranges and can be used with standard highway addressable remote transducer (HART) protocol modems. Also integrated on chip is a 5 ppm/°C internal reference, user-accessible offset and gain registers, and a 30 MHz serial peripheral interface (SPI) compatible interface.

This need makes the optimization of the available power budget one of the primary challenges facing system designers. To meet these requirements, system designers require a loop interface solution that is compact, power efficient, and highly accurate. Solution The AD5421, a complete transmitter solution, combines a precision 16-bit, loop-powered digital to 4 mA to 20 mA transmitter with on-board voltage regulation circuitry. The regulator generates a user-programmable 1.8 V to 12 V output voltage designed to power the AD5421 and the peripheral components within the smart transmitter. Consuming only 250 μA of quiescent current, the AD5421 conserves the system power budget enabling the selection of more accurate, higher power sensor electronics. Housed in a 28-lead TSSOP and 32-lead LFCSP (5 mm × 5 mm), the AD5421 offers a complete single chip solution that reduces the overall PCB component count, providing 55% footprint saving over alternative solutions.

Previously, 1 part per million (ppm) system design tasks entailed expensive and cumbersome implementations involving multiple lower resolution DACs with a significant number of discrete components and support ICs. Solution The AD5791 is the industry’s first single chip DAC to feature true 1 ppm resolution and accuracy, providing 4× greater accuracy and 4× more resolution than competing converters. The 20-bit AD5791 offers a relative accuracy specification of ±1 ppm INL maximum, and operation is guaranteed monotonic with a ±1 ppm DNL maximum specification. The product delivers 0.025 ppm low frequency noise, 7.5 nV/√Hz noise spectral density, 1 μs settling time, and 0.05 ppm/°C output drift. In addition, the device features sub-1 ppm lifetime drift. The output can be configured for standard unipolar (5 V, 10 V) or bipolar (±5 V, ±10 V) output ranges. The AD5791 uses a versatile 3-wire serial interface that operates at clock rates up to 35 MHz.

Processor Enhancements in processor technology that balance the price/performance ratio have had a positive impact on the adoption of sophisticated motor control designs in high volume applications. Leveraging these enhancements with ADI’s Blackfin and SHARC processors enables a better controller and control scheme, pushing the efficiency of motor control to nearly 100%. Within the industry, there is no doubt that the enhancement of multiple observer models running real-time model-based estimators will help to enhance performance of the drive, the system efficiency and topology, and the deployment method of the design. In regard to the deployment method of the design, graphical systems like MATLAB®/Simulink® are capable of easing the design flow and enhancing the development of new algorithms. With these tools—and the link to the executing processors—it becomes clear that a more complex deployment can be achieved. Processor-level enhancements centric to core speed, analog-to-digital conversion resolution, and memory integration will afford designers the capability and precision to achieve greater quality/performance objectives while accelerating time to market. With the recent introduction of ADI’s Blackfin ADSP-BF50x series of digital signal processors, significant processing performance gains have been achieved in parallel with price point reductions to bring DSP caliber performance to motor control applications previously serviced by performance constrained processors and microcontrollers. Motor system designers will leverage this performance profile to achieve greater system functionality and precision through the use of more advanced algorithms, which can be applied to accurately determine rotor shaft position and speed to eliminate the need for position/speed sensors in the system. The Blackfin ADSP-BF50x series exemplifies the aforementioned trend toward greater on-chip integration of components. This integration includes high resolution ADCs for precise data conversion and modeling accuracy and integrated flash memory to further speed algorithm processing—both of which minimize off-chip components and lower overall system costs. Processors offering an optimal blend of performance and on-chip integration enable designers to realize a number of system-level design objectives, including real-time processing of more data, reduced latency, consolidation of processing tasks to a single processor, and greater flexibility to optimize system interface and control capabilities. New technologies are pushing a paradigm shift in motor system capability, balancing design topologies and processor attributes to achieve greater overall system performance and efficiency. High performance DSPs enable modern control theory to be utilized in advanced system modeling, ensuring optimal power and control efficiency for any real-time motor system. The broad-based Blackfin ADSP-BF50x Processor Architecture application of sensorless vector control is now within reach and promises to accelerate the global movement toward more energy efficient and high performance industrial equipment.
