SMT16030 - SMARTEC

SMT16030 DIGITAL TEMPERATURE SENSOR

The SMT160-30 is a three terminal integrated temperature sensor, with a duty-cycle output. Two terminals are used for the power supply of 5 Volts and the third terminal carries the output signal. A duty cycle modulated output is used because this output is interpretable by a micro-processor without A-D converter, while the analogue information is still avail.

Features

Absolute accuracy ± 0.7 °C Linear output within 0.2 °C Resolution better then 0.005 °C Duty Cycle output Calibrated on chip TTL, CMOS compatible Temperature range 175 °C (-45 to +130 °C) Directly connectable to data input of microprocessor Easy multiplexing of multiple sensors Typical applications Heater systems Measuring instruments Washing machines Overheating protection Appliances Introduction The Smartec temperature sensor is a sophisticated full silicon temperature sensor with a digital output. The one wire output (duty-cycle modulated) can be directly connected to all kinds of micro-cont.
