The MCP2036 is an Analog Front End device that uses
the electromagnetic interaction between a conductive
target and a sensing coil to detect the pressure applied
by the user on the surface of a touch panel. The device
incorporates all analog blocks for a simple inductor
impedance measurement circuit.

For an inductive touch system, two methods are used
for switching the driver and measurement circuitry
between the different sensor coils: analog multiplexers
and GPIO grounding (see
