FUNCTIONAL DESCRIPTION
The MCP2036 measures a sensor coil’s impedance by
exciting the coil with a pulsed DC current and
measuring the amplitude of the resulting AC voltage
waveform. The drive current is generated by the
on-chip current amplifier/driver which takes the
high-frequency triangular waveform present on the
DRVIN input, and amplifies it into the pulsed DC current
for exciting the series combination of the sensor coils.
The AC voltages generated across the coils, are then
capacitively coupled into the LBTN and LREF inputs.
An input resistance of 2K between the inputs and the
virtual ground offsets the AC input voltages up to the
signal ground generated by the reference voltage
generator, as shown in Figure 1-1.
