GENERAL DESCRIPTION
The ADUX1001i is a high efficiency linear resonant actuator
(LRA) controller that uses the Analog Devices, Inc., proprie-
tary Actuator Response Control™ (ARC™) technology. The
ADUX1001i control algorithm detects LRA resonant fre
quency and provides closed-loop control of drive frequency
and magnitude, ensuring compelling, reliable, and repeatable
haptic effects for all portable, gaming, and handheld applications.
The ADUX1001i features an 8-bit digital-to-analog converter
(DAC) that has programmable, bi-directional output current
capability. The hardware shutdown mode ensures low power
operation over a full 2.3 V to 4.8 V supply range, making it
ideally suited for portable mobile device haptic applications.
The ADUX1001i is compatible with Immersion TS3000 and
Immersion TS4000 engines.
The ADUX1001i features three interface options ensuring that
the ADUX1001i can be used in existing haptic implementations
as well as in new low latency haptic implementations. The
operating modes of the controller are invoked by the ADUX1001i
using a PWM- and/or an I2C-compatible interface. The I2C
7-bit address for the ADUX1001i is programmable using two

external pins.
