LDS6003
PureTouch Capacitance Touch IC
The LDS6003 PureTouch controller empowers system designers to create streamlined, attractive,
and reliable product designs, enabling the replacement of mechanical controls with capacitive touch
buttons, sliders, and scroll wheels.
Description
The LDS6003 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.
Featuring 6 sensor inputs, the LDS6003 provides the flexibility to implement multiple touch inputs using
a single controller.
The capacitive sensor inputs are directed through an integrated switch matrix to a 500 kHz sigma-delta
CDC which senses changes in the external sensor array. When a sufficiently large change in capacitance
occurs, a sensor activation is registered and the host processor is notified.
On-chip calibration logic continuously monitors the environment and automatically adjusts on-and-off
threshold levels to prevent false sensor activation. The LDS6003 is offered with both SPI-compatible and
I
2C-compatible interfaces (active interface selected by I/F select pin) and features a general-purpose input/
output (GPIO) and interrupt output for additional communication with the host processor.
