Violin Servo Amplifier

miniature servo drive for DC brush motors 

The Violin series of miniature servo amplifiers for DC brush motors incorporates custom mixed analog/digital ICs and a hybrid power stage.

The basic configuration is a current mode amplifier targeting the OEM market.
No trimmers are used in the basic version.
The product meets UL508c and relevant CE regulations.
The power stage is implemented on a single ceramic substrate. This design enables very high thermal conductivity, high current carrying capacity, better EMC and good mechanical strength.
The control section is implemented by dedicated custom ICs which contribute to higher reliability through lower component count and improved performance Through board-level Integration.
