systems for cars and model craft. With the addition of only a few components as shown in the diagram, the device produces an ear-splitting sound of 120 dB. The IC contains an a. f. rectangular-wave generator that is driven by a sawtooth generator. The sawtooth sweeps the output frequency range (sweep 2:1) once every second. The frequencies of both oscillators are dependent on an internal 61. 5 k © resistor and an external resistor, RT=<1M ©, and capacitors CMOD and COUT. The output driver has an inverting and a non-inverting output. The simplest application of the ZSD100 is shown in Figure 2 in which the sound is produced by a piezo buzzer. If a dynamic 6 © loudspeaker is used, it is connected in an H-bridge, that is, driven symmetrically. The value of resistor RT must then be small, or the relevant pin must be strapped to earth.
