BLOCK AND APPLICATION DIAGRAM

Figure 1. Typical application circuit (max 18Vpp signal for piezo from 3V supply voltage)

Note: In capacitance decrease detection (DSEL=GND) the RINC resistor is not needed and it is replaced by a

short circuit (0

). Similarly, in capacitance increase detection (DSEL=VIN) the RDEC resistor is not needed and it

is replaced by a short circuit (0

).
