The DA7282 ultra-low power haptic driver, combines custom drive sequences, on- and off-resonance, at up to 1kHz. The DA7282 drives both ERM and LRA (narrow and wideband) actuators and track resonance up to 300Hz producing highly complex click/vibration touch effects in a wide range of applications.

The DA7282 differs from the DA7280 and DA7281 by providing the capability to go into a full standby mode, lowering current consumption to 5nA.


  • 20x lower standby current, minimizing the drain on small battery systems
  • Constant resonance frequency tracking through continuous current drive monitoring
  • Ultra-low power consumption meaning longer battery life
  • Only 0.75ms latency when responding from ultra-low power state
  • Drives LRAs off-resonance for custom effects, or dual-resonant systems for two-dimensional vibration
  • Enables wideband effects as well as supporting dual-resonant systems
  • Drives distinct haptic effects triggered by multiple inputs without need to wake the host processor
  • Detects issues with motor automatically
  • Frequency, time, amplitude triplets to program the waveform
  • Quick and easy software development using the SmartCanvas™ GUI


  • 5nA standby current consumption
  • Wideband LRA driver: 25Hz to 1kHz with resonant mode
  • Frequency tracking support up to 300Hz
  • Low-latency direct drive for haptics
  • On-the-fly diagnostics
  • Custom waveform sequences
  • Three methods of drive with Linux and C-like driver (HAL)
  • Packages
