LDS6005

PureTouch™ Capacitance Touch IC

The LDS6005 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

LDS6005 Features

The LDS6005 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 10 sensor inputs, the LDS6005 provides the ﬂexibility to implement multiple touch inputs using

a single controller.

Versatile, accurate capacitance-

to-digital converter (CDC)

•ꢀ 10ꢀcapacitanceꢀsensorꢀinputꢀchannels

•ꢀ 2ꢀmsꢀupdateꢀrateꢀperꢀactiveꢀsensor

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.

Integrated, automatic

calibration algorithms

•ꢀ Environmentalꢀcompensation

On-chip calibration logic continuously monitors the environment and automatically adjusts on-and-off

threshold levels to prevent false sensor activation. The LDS6005 is offered with both SPI-compatible

and I²C-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.
