Description
The DA7280-A high-definition (HD) haptic driver combines custom drive sequences, on- and off-resonance, at up to 1kHz. The DA7280-A can drive both ERM and LRA (narrow and wideband) actuators and track resonance up to 300Hz to drive the most complex click/vibration touch effects in a wide range of applications.
The DA7280-A combines very low idle current consumption (360nA) with low-latency trigger inputs to minimize the delay after button presses when an application process is in deep sleep.
This product is AEC-Q100 Grade 2 qualified and is perfect for being deployed in automotive applications where haptic feedback is required. DA7280-A comes in a 12-pin Wettable flank QFN (3x3mm).
