APPLICATIONS CIRCUITS
Piezo Sounder
Utilizing a standard autotransformer driven piezo sounder, this circuit indicates a minimum
component count alarm solution. In this configuration a ZTX605 darlington transistor can be
connected directly to the ouput of the IC without the need for base resistors.
Moving Coil Loudspeaker Sounder
Moving coil loudspeakers are often used for the very highest output automotive alarm sounders. The
ZSD100 complementary outputs, with the selection of ZTX790A and ZTX690B transistors, can drive
this H bridge ouput circuit without any additional interface components.
