Texas Instruments latest AMC series functionally isolated ADC modulators can provide dexterity for assembly tasks requiring increased precision, including for humanoid robots.
Electrical components provider Texas Instruments (TI) recently introduced new functionally isolated modulators, which can help robot designers achieve more precise motor control in compact designs.
The new AMC0106M05, AMC0136 and AMC0106M25 isolated modulators can enable increased precision and higher resolution of 12 to 14 effective number of bits (ENOB) for accurate and reliable phase current sensing and DC voltage sensing measurements.
Offered in a small leadless package, TI said the new products in its isolated analog-to-digital converter (ADC) portfolio can help designers achieve smooth torque operation and fine motor control, while decreasing size and cost in robot designs under 60 volts.
Production quantities of the new functionally isolated modulators are available now on the company’s website in an 8-pin very thin small-outline (VSON) package. To support designers, evaluation modules for all three modulators are available, as well as reference designs and simulation models.
Engineers today are challenged to design smarter robots to perform more detailed tasks. TI said its galvanically isolated modulators can enable robot systems engineers to achieve precise motor control and system protection in smaller, more sophisticated designs. This precision makes it possible for robots to complete a variety of complex tasks, such as threading a needle or handling small nuts and bolts, such as for pick-and-place or assembly.
In addition, the new modulators measure 3.5 by 2.7 millimeters. TI said its small modulators require 50% less board space than other reinforced isolation components. With this decrease in size, designers have more space to incorporate additional features that support precise control and reliable operation in compact robot applications.
“These modulators from TI enable designers to increase robotics accuracy and productivity in new use cases and smaller form factors, from the factory floor to the operating room,” said Karthik Vasanth, TI VP & GM of data converters and clocks. "For example, where humanoid robots could previously only complete simple tasks, our new functionally isolated modulators now allow them to carry out more dexterous and precise jobs.”
