LDS6010
PureTouch™ Capacitance Touch IC with Integrated
VibeTonz®-Ready Haptics Driver
The LDS6010 is a programmable capacitance-to-digital converter (CDC)
designed for use with capacitive sensor arrays implementing touch-based
input controls including sliders, scroll wheels, and buttons. A built-in
VibeTonz®-Ready haptics driver enables efficient integration of advanced
tactile feedback without the need for a separate IC. Touch sensor inputs
are directed through an integrated switch matrix to a 16-bit 500 kHz sigma-
delta CDC which senses changes in the external sensor array. Featuring 15
sensor inputs, the LDS6010 provides the flexibility required to implement
multiple tactile-enabled touch inputs using a single controller.
On-chip calibration logic continuously monitors the environment and
automatically adjusts on-and-off threshold levels to prevent false sensor
activation.
The LDS6010 is offered with both SPI-compatible and I2C-compat-
ible interfaces (active interface selected by I/F Toggle pin) and features
a general-purpose input/output (GPIO) and interrupt output for additional
communication with the host processor.
