digital potentiometer

  1. Tiny display needed

    Hunting for any and all help I can get. I'm wanting to design a small circuit that uses a digital potentiometer in place of a mechanical one but I can't come up with a tiny (fit-on-the-board) display that will give me some indication of the wiper position of the digital pot. Any suggestion for...

    AD5220 digipot goes to limit in 1 pulse

    good day, I got a AD5220 digital poti and data sheet says, I only need so switch a push button to change the resistance. Off course also need to select up / down and pull CS low to enable. And get a pull up resistor happening (which is not in the manual, but you need it). But as soon as I pull...

    Circuit bricks Nano (power supply)

    Hi, I am making a module for a DIY modular synthesizer. The module applies an ADSR-envelope to an audio signal using a 10K MPC41010 digital potentiometer. I suspect, I made an error in the circuit, since I now have 2 Nano's which will not power on from USB (pwr led flashes a few times and then...
  4. Non-Linear Resistance Control

    All, I’m working a project in which I will need to control the output of a DC/DC converter using a microcontroller. I’m planning on using the LM27402 DC/DC Controller IC from TI. My application circuit will be very similar to the circuit taken from page 2 of the evaluation board datasheet and...
