PRECISION HIGH VOLTAGE
Analog Devices’ precision high voltage signal chains combine precision high voltage amplifiers, high voltage digital-to-analog converters (DACs), difference amplifiers, and matched resistor networks. Drive signal chains are offered at several voltage, current drive, density, and slew rates, allowing system designers to find a solution optimized for their needs. Each signal chain provides example solutions to drive high voltage signals up to 216 V or drive currents up to 2 A.
Precision high voltage measurement signal chains support a range of common-mode voltages, allowing users to interchange density, dynamic range, and accuracy depending on their application needs. These signal chains provide examples to measure large differential signals up to 220 V or small differential signals with a large common-mode voltage.
Find tailored drive and measure solutions suitable for high voltage ATE, automotive test, and source measurement units (SMUs). Drive solutions are tailored for piezoelectric positioning and actuation, and MEMS mirror control applications by varying density, drive voltage, drive current, and protection features.
