|
The AD7143 is an integrated capacitance-to-digital converter (CDC) with on-chip environmental calibration for use in systems requiring a novel user input method. The AD7143 interfaces to external capacitance sensors implementing functions, such as capacitive buttons, scroll bars, and scroll wheels. The CDC has eight inputs channeled through a switch matrix to a 16-bit, 250 kHz sigma-delta (∑-Δ)...
