Description

The NST1075 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 typical accuracy of ±0.5°C without calibration or signal adjustment from external components. NST1075 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 NST1075 is compatible with SMBus and I2C interface, allowing a maximum of 27 devices to be connected to one bus and supporting the SMBus alarm function. The NST1075 has an operating temperature range of -55 °C to 125 °C and is ideal for extended temperature measurement in a wide range of communications, computing, consumer products, Internet of Things, environmental, industrial and instrumentation applications. NST1075 is packaged with WSON8 and the size is 2.0mm×2.0mm, which can better meet the temperature measurement requirements of miniaturized devices such as routers.

Features

• High accuracy over -55°C to 125°C Wide Temperature Range
• -20°C ~85°C: ±0.5°C (Typical)
• -20°C ~85°C: ±1°C (Maximum)
• -55°C ~125°C: ±1.5°C (Maximum)
• Maximum resolution: 0.0625℃, optional
• Up to 27 device addresses supported
• Wide supply voltage range: 1.62V to 5.5V
