  • RE: DRV2665: Generate programmable constant +/-DC output

    Resolved
    Hi, Anvesh, Welcome to E2E and thank you for your interest in our products! I think the best solution for this would be use an analog input (PWM or ADC) but removing the input capacitors from the DRV2665 input. The input capacitors work as a DC blocking…

  • DRV2665: Can this part drive a piezo chip with the DC voltage needed to hold it in the actuated position?

    Part Number: DRV2665 Other Parts Discussed in Thread: DRV8662 From the datasheet it is not clear if the output is an AC waveform only. I need the hold the actuator in potions not cycle quickly back and forth. Will this IC support this need? I need full…

  • RE: Using DRV2665 or DRV2667 to provide a programmable low-current DC voltage supply for 0--100v, 0.5ma?

    Resolved
    Hey Mike, Let me elaborate a little more. The PWM signal from the uC would be filtered down to a DC level. This will change the current from Vfb to PWM (ie, as the DC value of the PWM signal increases, the voltage across the resistor decreases, and…
