Precision High Voltage Solutions
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 currents up to 2 A.
Precision high-voltage measurement signal chains support a range of common-mode voltages, allowing interchangeable density, dynamic range, and accuracy depending on 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.
