MTC8104ESI（-L）Specification V1.0

Mtc8104esi touch sensing IC is an integrated circuit designed to realize human touch interface. It can replace the mechanical touch button to realize waterproof and dustproof, sealed and isolated, solid and beautiful operation interface. One mtc8104esi can realize 1 to 4 independent keys, and users can use them flexibly according to their needs.

Technical mechanism

Mtc8104esi uses 16bit high-precision CDC (digital capacitance converter) IC to detect the capacitance change on the sensing disk (capacitance sensor) to recognize the touch action of others' fingers. The data output by CDC is processed by the embedded RISC processor with efficient and reliable algorithm. Directly output high and low level to indicate key action.

High production efficiency

Just adjust one capacitor CSEL to change the sensitivity of all channels. Less peripheral components and high production efficiency.

Adapt to different thickness panels

The mtc8104esi can adapt to different thickness insulation panels of 0-20mm by selecting the appropriate capacitance value of CSEL and adjusting the area of the induction disk.

Chip packaging form

Mtc8104esi is packaged in standard 16pin NSOP.
