Description
• Switching Initiated by Damping of Internal Oscillator
The CA3165 is a single chip electronic switching circuit
intended primarily for ignition applications. It includes an
oscillator that is amplitude-modulated by the rotor teeth of a
distributor, a detector that develops the positive going modu-
lation envelope, a Schmitt trigger that eliminates switching
• Proximity Sensing of Rotational Motion
