The NST235 is a high precision CMOS analog output temperature sensor. The device offers a maximum accuracy of ±0.5°C at 25°C and a maximum of ±2.5°C over the full temperature range. The device is specified at the full temperature range of -40°C to 150°C and the power supply operating range is 2.3V to 5.5V.

The NST235 device provides a positive slope output of 10.0mV/°C over -40°C to 100°C. it is highly linear and does not require complex calculations or lookup tables to derive temperature. The NST235 is a low power device, and the typical operating current is 20μA. Therefore, self-heating is negligible.

The NST235 is available in SC70(5) and SOT23(3) package, making it suitable for on-board and offline applications in the industrial, and consumer markets applications in the IoT.
