    Gonzalo, The EVM kit does not include a Piezo actuator at the moment, but we hope to include one soon. Here are a few Piezo actuator vendors: AAC Technologies (recommended) Murata NEC-Tokin Hokuriku Thanks, Brian

    Lower voltage and Lower PCB foot print - I purchased the DRV8662EVM, and look for ways of achieving Lower PCB foot print (at the expense of Lower voltage). Can the DRV8662 be operated without the L1, C1 to achieve lower foot print ? No. Boost Inductor and Boost capacitor are required for Boost...

    Brian Burk
    Kanhu, Please see section "3.4 Filtering and Adapting PWM Waveforms" in the DRV8662EVM User's Guide to change the bandwidth of the DRV8662EVM. You will need to adjust the input filter to the DRV8662 so that the filter cut-off frequency is higher than 1kHz. If your input is a sine...

    Ole, The AAC actuators are not stocked by distributors at this time. The best option is to contact AAC directly through their website to request information and samples. http://www.aacelectr.com/en/about/contact.asp Thanks, Brian

    Hi Ole, Mide Technology (disclaimer: I work here!) also has a line of hermetically sealed piezo bimorph products ( http://www.mide.com/products/qp/qp_catalog.php#actuator ) that work well over the DRV8662's output voltage range. They are probably more expensive than some others in small quantities...

  • Forum Post: RE: How to obtain the full datasheet and specification for the DRV2665?

    David Sweeney
    Hello again, Is any documentation for the DRV2667 IC or the DRV2667 evaluation module available yet? At the very least, it would be great to have the device's pinout - but the i2c command set, or better still, the complete specification would be fantastic. Thanks for your assistance
