FAH4840 Haptic Driver

The FAH4840 is a high-performance amplifier for mobile phones and other hand-held devices. The haptic driver takes a single-ended PWM input signal to control a Linear Resonant Actuator (LRA). The device utilizes an external 10 kHz to 250 kHz PWM signal capable of meeting the wide range of resonant f.
