ON Semiconductor, driving energy efficient innovations, has introduced a new touch/proximity sensing solution that combines industry-leading performance, cost effectiveness and convenience in a single chip. The LC717A30UJ high dynamic range capacitance-to-digital converter uses mutual capacitance to detect changes in capacitance down to femtofarad (fF) levels. Parasitic capacitance cancellation raises the detector sensitivity, while its built-in noise rejection mechanism combats the effects of electromagnetic interference (EMI).
