The Mobile Inductive Touch LDC Devices, the LDC3114 as well as the 2-channel LDC2112 and the 4-channel LDC2114, are high-resolution LDCs with internal algorithms optimized for Inductive Touch applications. The internal algorithms extract inductance shifts corresponding to button presses and can report the event through dedicated output pins. A dedicated sensor per channel can detect sensor frequency shifts corresponding to metal deflection smaller than 200 nm. The sensor frequency can go up to 30 MHz, which enables circular buttons as small as 2.4 mm and rectangular buttons smaller than 2.0 mm by 7.0 mm. LDC3114 and LDC2112/4 sensors can be constructed on PCBs or flex PCBs.
The main features of this family of LDCs include:
