    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

    Eric - this is an excellent article! When you discuss power efficiencies between ERMs, LRAs, and Piezoelectric Actuators, your article appears to relate only vibrations on mobile handsets or handheld devices. When we have applications of vibrations in the 18-38Hz range using ERMs (and customized LRAs...

    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...

    Hi, Yeah, I am still waiting for a reply from AAC, will give them a call towards the end of the week. I am considering actuators from Steminc, but are still awaiting a data sheet. Here is a link: http://www.steminc.com/piezo/SMBTA352D2T07M.asp Cheers, Ole

    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...

    LeonardEllis
    The DRV2605 IC has the Haptic control firmware built-in to the device, so the uC or Processor in the system does not have to generate PWM to activate the Haptic (vibrating) device. There are "canned" routines included, you can use any from the library without license or royalty fees, and yes...

    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
