CEDRAT TECHNOLOGIES is now promoting microcontrollerbased solutions for controlling piezo-actuators. Microcontrollers provide powerful digital signal processing capability with reduced size and cost, allowing embedded applications to be targeted. The new UC45 board uses a microcontroller to provide fully-digital control of piezo-actuators at 10KHz. It features ADC and DAC with 16-bit resolution, for applications where high resolution is required, such as ultraprecise positioning.
