Functional Description (cont’d)

An RC combination is needed to generate the fundamental frequency (pin ROSC , COSC). The volume

can be adjusted with another resistor (pin L). The loudspeaker must be connected directly between

the output Q and the power supply VS . The current-sink principle combined with an integrated

thermal shutdown (with hysteresis) makes the IC overload-protected and shortcircuit-protected.

There are two trigger pins (E1, E2) for setting single-tone, dual-tone or triple-tone mode.
