Ideal solution for portable applications

The LDS6003 is optimized for minimal power consumption, with touch sensor circuits operating from a

1.8V supply voltage. In full power mode, sensor conversion and calibration occur continuously, minimizing

the time between touch event and touch detection. With its ultra-low touch sensor power consumption of

<150 uW (typical), the LDS6003 may be operated continuously in full power mode, even when battery life

is of premium importance. The low power architecture of the IDT PureTouch™ solutions eliminates the

need for introduced latency periods that can cause noticeable delays and degrade the user experience.

When touch inputs are not required to be active, the LDS6003 may be put into standby mode, reducing

typical power consumption below 1 uW.
