ATLAS® Digital Amplifiers
High performance torque control for brushless DC, DC brush, and Step motor control.
ATLAS® Digital Amplifiers are compact single-axis amplifiers that provide high performance torque control of DC brush, brushless DC, and step motors. They are packaged in a compact solderable module and utilize standard through-hole pins for all connections.

High Performance in an Ultra Compact Package
ATLAS Digital Amplifiers are used for direct control of motor torque, or in conjunction with higher level controllers for velocity or positioning applications. Their very compact size and high power output make them ideally suited for applications such as laboratory automation, scientific instruments, general purpose motion control, HVAC, fan & pump controllers, and industrial motor control applications. ATLAS Amplifiers are provided in both vertical and horizontal mounting configurations, and with and without heat sink attachment tabs.
ATLAS digital amplifiers provide many advanced control features including user-programmable gain parameters, performance trace, field oriented control, and I2T current management. Atlas amplifiers are powered from a single supply voltage, and provide automatic protection from overcurrent, undervoltage, overvoltage, overtemperature, and short circuit faults.
The ATLAS family has been designed to work seamlessly with PMD's Magellan family of Motion Processor ICs. Alternatively, they can be used with dedicated FPGAs, digital signal processors, or general purpose microprocessors. Communication is via SPI (Serial Peripheral Interface) using a simple, packet-oriented protocol. For step motors, in addition to the SPI format a dedicated pulse & direction input mode is provided.
