    Part Number: DRV2667 Other Parts Discussed in Thread: DRV2665 How is it that the DRV2667 when powered from 3V3 or 5V can output > 100V to drive an actuator? How is this amplification beyond the supply rail possible? Thank you

  • DRV2667: Freq 20hz - 20khz, 50Vpp for 6.8uF Piezo speaker

    Part Number: DRV2667 Other Parts Discussed in Thread: LM48580 , DRV5825P Can DRV2667 drive 6.8uF piezo speaker for 20-20kHz (audio output) @50Vpp?

  • RE: DRV2667: How can we vibrate the piezo haptic actuator with DRV2667

    Thanks for reply I will do this. Moreover I want to know , can we use haptic console software with our drv2667 circuit?

  • DRV2667: DRV2667 driving with square wave for Piezo actuator

    Part Number: DRV2667 Hi there, I have been using the DRV2667 for the last year or so to drive piezo stacks from Thorlabs as micro-actuators. We have been using the chip to output 100Vpp to 200Vpp square waves to quickly and sharply increase the length…

  • DRV2667: Does the device output Boost Voltage on powering up without any software initialization process?

    Resolved
    Part Number: DRV2667 I expect DRV2667 to output Boost Voltage on powering up, but it does not. I guess the device should be initialised by software before it outputs Boost voltage. Does the step 3 in the following figure mean I need to clear standby bit…
