PI nanopositioning controller provides 500 mA peak current
The E-754 nanopositioning controller is designed for closed-loop piezo mechanisms with capacitive position feedback sensors. Its servo has a 50 kHz update rate and 22-bit resolution. Digital linearization based on fourth-order polynomials suppresses linearity deviation to <0.01%. The driver provides 500 mA peak current and -30–135 V output voltage swing.
