INTRODUCTION
●The ZSD100 is a frequency swept alarm signal generator designed specifically for static and automotive security alarm systems. One ZSD100, two timing capacitors, an in-expensive TO92 darlington, piezo transducer and coupling transformer is all that is necessary to produce an ear piercing 120 dB alarm siren.
●FEATURES
●• 4-18V Operating voltage range.
●• Small external component count.
●• Direct drive of darlington, mosfet and IGBT output stages.
●• Single ended or push-pull output stages.
●• Suitable for automotive and static alarm systems.
●• Low supply current - 10mA operating
● - 1µA sleep mode
●• Low cost 8 pin DIL & SO packages.
●• User selected audio and sweep frequencies.
●• -40°C to 125°C operating temperature range.
●• Choice of modulation waveform.
