I2C/SMBus Interface Digital Temperature Sensor with Automotive-Grade Standard Packaging
>
The NST175-Q1 is a low-power, high-precision digital temperature sensor ideal as an alternative to negative temperature coefficient (NTC) and positive temperature coefficient (PTC) thermistors. The device provides max accuracy of ±0.5 °C without calibration or signal adjustment from external components. NST175-Q1 temperature sensor is a highly linear product, which can sense the temperature without complex calculation or lookup. The on-chip 12-bit analog-to-digital converter (ADC) provides resolution as low as 0.0625 ° C. The NST175 is compatible with SMBus and I2C, allowing a maximum of 27 devices to be connected to one BUS and supporting the SMBus alarm function. The NST175 has a rated operating range of -40 °C to 125 °C and is ideal for extended temperature measurement in a wide range of automotive applications. NST175-Q1 comes in industry-qualified MSOP8 and SOP8 packages.
