A variable resistor that integrates a programmable, temperature-indexed look-up table can compensate for the temperature drift of a voltage regulator. In this case, the look-up table can change the ...

Pickering Interfaces has announced a new family of PXI and PXIe programmable resistor modules, its first that can handle up to 2A and 200V (or as limited by max power). Credit: Pickering Interface ...

For many variable resistor (rheostat) applications, one of the device’s terminals is connected to a voltage source VS. Such a source might be a reference DC voltage, an op amp output carrying an AC ...

Pickering Interfaces has announced a family of 1,200V programmable resistor modules in a single-slot PXI or PXIe form factor. 40-230 is the PXI series, and 42-230 boards have a PXIe interface* – there ...

Pickering Interfaces has launched a family of 110 programmable resistor modules with 2.5W, 5W or 10W power handling capability at 100V or as limited by power. Models 40-251 (2.5W), 40-252 (5W) and ...

Ningbo Joyson Electronic has been granted a patent for a programmable resistance circuit that configures selected resistances using a reference resistor. The circuit utilizes a modulated voltage ...
