The MCP4231 digital potentiometer circuit that we will build to control the brightness of 2 ultra low-current LEDs, alternating between the 2 so that one is fully bright while the other is off, is shown below. The LEDs must be low-current, because the maximum current that can pass through...
The invention provides a 4-20 mA current loop circuit controlled by a digital potentiometer. Input ends of photoelectric couplers U1, U2 and U3 respectively receive chip selection signals, clock signals and data input signals of the digital potentiometer, all of which are sent by a microprocessor...
In this Circuit, digital potentiometer, connect pushbutton switches to fast and slow with one end to +7.5V, when you hold the button down the analog voltage will ramp up-down, fast or slow, this will enable you to make a digitally controlled millivolt source or power supply. ...
Linearizing the potentiometer using a series-parallel combination could be quite complex, as shown in the equivalent circuit of Figure 5, Figure 5. Final Y-∆ transform. where: the feedback input pin typically has high impedance, so the effect of R6can be made negligible. ...
