    Quad 100k Digital Rheostat - Can it be wired for 300k?

    Hi, I have a Fairchild FL51x0 which has a control pin where the voltage at the pin is input to an 8 bit ADC with 2.5V reference. The pin sources 10uA current, so that an external resistor can be used to set the voltage (0-250k). I'd like to use a Digital Potentiometer/Rheostat. However, the...

    High Frequency Variable Resistor

    Hi, I'm looking for a variable resistor (rheostat) able to operate also with high frequency current. In particular, for my application, the current is sinusoidal with f=100kHz and amplitude of 40A. The range of variable resistance should be 0-200 Ohm and 0-10 kOhm (obviously for higher value...
