Integrating with existing piezo-based nanpositioning systems and piezo actuators, E-727 features 20-bit DACs and ADCs, 4 PAs, PID control, and 2 programmable notch filters. Closed-loop nanopositioning systems are supported with capacitive feedback sensors, piezoresistive sensors, and strain gauges. Linearization fosters positioning accuracy, and DDL eliminates non-linearities at high frequencies. Data recorder, ID chip compatibility, and programmable drift compensation are also standard.
