Description

The NST5851 is a low-power, high-precision digital temperature sensor, an ideal replacement for negative temperature coefficient (NTC) and positive temperature coefficient (PTC) thermistors. It provides typical accuracy of ±0.2 without the need for calibration or external component signal conditioning. The NST5851 temperature sensor is highly linear, allowing temperature to be known without complex calculations or look-up tables. The on-chip 12-bit analog-to-digital converter (ADC) provides a resolution as low as 0.0625℃. The NST5851 is compatible with SMBus and I2C interfaces, allowing up to 9 devices on a single bus and supporting SMBus alert functionality. The NST5851 operates over a temperature range of -40℃ to 125℃, making it an ideal choice for extended temperature measurements in a variety of communications, computer, consumer, IoT, environmental, industrial, and instrumentation applications. The NST5851 is available in an industry-standard SOT23-6 package.
