CS209A Overview
CS209A Proximity Detector The CS209A is a bipolar monolithic integrated circuit for use in metal detection/proximity sensing applications. The IC (see Figure 1) contains two on−chip current regulators, oscillator and low−level feedback circuitry, peak detection/demodulation circuit, a parator and two plementary output stages. The oscillator, along with an external LC network, provides controlled oscillations where...
