CS209A Datasheet Proximity Detector

Manufacturer: Cherry Semiconductor

Overview: CS209A CS209A Proximity Detector.

General Description

The CS209A is a bipolar monolithic integrated circuit for use in metal detection/proximity sensing applications.

The IC (see block diagram) 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 amplitude is highly dependent on the Q of the LC tank.
