The Tango S32 is a general purpose capacitive sensor, with a bidirectional serial interface (SPI). It senses variations of capacitance using an innovative proprietary concept. This architecture simplifies the application development and allows the user to create customized solutions.
Its special capabilities make the system insensitive to environmental conditions such as temperature, humidity and also other variations. The chip adapts itself to large series resistance of long lines, especially seen when using ITO technology. The device has very low power consumption. The clock is derived from the SPI interface and when the chip is not selected; the current is typically 100 nA.
