PI (Physik Instrumente) L.P. Reference Class Digital Piezo Controller E-754

E-754 is a single-axis digital piezo controller for nanopositioning systems with capacitive sensors, featuring a 375 MHz DSP/ARM processor and 50 kHz servo and sensor sampling rates. It delivers up to 135 V output voltage with 45 W peak power and 500 mA peak current, supported by a 22-bit effective DAC and 20-bit analog I/O. The controller includes ID chip auto-calibration, a wave generator, data recorder, and macros for stand-alone operation. Interfaces include Ethernet (TCP/IP), USB, RS-232, and SPI, with LEMO connectors for analog and digital I/O. It operates from a 24 V DC power supply, consumes 35 W maximum, and measures 1.6 kg in mass. Operating temperature ranges from 5 to 40 °C, with overheat protection that disables the piezo output above 70 °C.
