M-982-02 Datasheet (Clare Inc.) - Precise Call Progress Tone Detector

M-982-02, Precise Call Progress Tone Detector

The M-982-02 is an integrated circuit precise tone detector for special-purpose use in automatic following of switched telephone calls.

The circuit uses lowpower CMOS techniques to provide the complete filtering and control required for this function.

The basic timing of the M-982-02 is designed to
