Introduction

The SMT172 is an ultra-low power, high-precision temperature sensor that combines the ease of use with

the world’s leading performance over a wide temperature range. Using the most recent advances in the

silicon temperature sensing technology, the SMT172 has applied some really sophisticated IC design

techniques as well as high-precision calibration methods, to achieve an absolute inaccuracy of less than

0.1°C in the range of -20°C to 60°C

The SMT172 operates with a supply voltage from 2.7V to 5.5V. The typical active current of only 60µA, the

high speed conversion over 4000 outputs per second (at room temperature) and an extremely low noise

makes this sensor the most energy efficient temperature sensor in the world (0.36µJ/measurement).

The SMT172 has a pulse width modulated (PWM) output signal, where the duty cycle is proportional to the

measured temperature. This makes it possible that the sensor can directly interface to a MCU without using

an Analog-to-Digital Converter (ADC). Today, the hardware Timer in a MCU to read our PWM signal has

become available almost universally, fast in speed and low in cost. Therefore, it is extremely easy for any

user to get started with this sensor and achieve a very quick time to market.
