ATLAS Digital Amplifiers Expand Flexibility with New Communication Capabilities

PMD announced that its ATLAS® digital amplifiers, featuring the highest power density in the industry, can now be used with third party microprocessors or field programmable gate arrays (FPGAs) via Serial Peripheral Interface (SPI) communications.

ATLAS Digital Amplifier Has New Communication CapabilitiesOriginally designed to be used in conjunction with Performance Motion Devices’ 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.
