Digital Amps Expand Add More Communication Capabilities

(Performance Motion Devices)

Performance Motion Devices’ ATLAS digital amplifiers can now be used with third party microprocessors or field programmable gate arrays (FPGAs) via Serial Peripheral Interface (SPI) communications. Originally designed for use with the company’s Magellan motion control ICs, ATLAS digital amplifiers can now communicate through SPI with third party controllers, significantly increasing the range of applications and designs where ATLAS can be deployed. ATLAS digital amplifiers are suitable for robotics, medical devices, laboratory equipment, scientific instruments, fan and pump control, precision motion and industrial motor control.


The amplifiers are compact single-axis modules that provide torque control of dc brush, brushless dc, and step motors. ATLAS versions are available in 75W, 250W, and 500W power configurations in two module sizes: 27 x 27 x 13mm and 39 x 39 x 15mm. Package options allow the amps to be mounted to a printed circuit board in either vertical or horizontal configurations. For more details, the ATLAS datasheet awaits perusal as well as the Atlas Digital Amplifier User's Manual and Atlas Digital Amplifier Complete Technical Reference.
