CAPACITANCE TOUCH FAMILY FLYER
Ideal Solution for Portable and “Green” Applications
The LDS6100/6120 is optimized for ultra-low power consumption. 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 current consumption of <70 μA (typical at 1.8V), the LDS6100 products may be
operated continuously in full power mode, eliminating the need for introduced latencies that can cause
noticeable delays and degrade the user experience. Where power consumption is of the utmost
importance, low power modes with configurable latencies may be utilized to further reduce current
below 25 μA (100ms sleep cycle).
The LDS6100/6120 family is optimized for a minimized solution footprint, with the functionality of multiple
components consolidated into a single device and a bare minimum of required external passive
components. A variety of package options are available including a 4mm x 4mm 28 lead TQFN package, a
5mm x 5mm 40 lead TQFN package (both with 0.75mm package thickness), or a 5.3mm x 10.2mm SSOP
package for applications requiring a wider lead pitch.
*For direct application of 1.8V voltage. For voltages higher than 1.8V, apply voltage to VDDIO and tie VDD1 to ground though C2.
