General Description

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 frequencies needed for an LRA haptics applications.
