Piezo Driver

altNewport Corp. (Irvine, CA) offers the XPSDRVP1, an XPS-compatible driver card for the piezoelectric stack-based NanoPositioning line of sub-nanometer-resolution stages. The driver eliminates the need for either an XPS pass-through card or an independent piezostack driver. An erasable programmable readonly memory (EPROM) stores the stage parameters in the connector, which also has embedded ESP plug-and-play technology that auto-uploads the stage ID and all necessary stage settings to the XPS. The single-axis driver features 60mA peak current, with an internal loop rate of 4 kHz. It can drive both open loop and closed loop NanoPositioning stages equipped with strain gage position sensors.
