ZHCSDR2A April 2015 – October 2024 FDC1004-Q1
PRODUCTION DATA
Figure 7-3 below is optimized for applications where the sensor is not too far from the FDC1004-Q1. Each channel trace runs between 2 shield traces. This layout allows the measurements of 4 single ended capacitance or 2 differential capacitance. The ground plane needs to be far from the channel traces, it is mandatory around or below the I2C pin.
