Detailed Product Description

UL NTC Temperature Sensor

Quick Detail:

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

Description:

The 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-controllers without the need of A/D conversion. The temperature range is –45

°C to 150 °C. The high resolution (< 0.005 °C) makes the sensor useful for high precision

applications. The sensor is available in various housings like T018, T092, T0220 and for high

volume production in SOIC. Special housing can be manufactured on request.

Applications:

Heater systems

Measuring instruments

Washing machines

Overheating protection

Appliances
