TMP64-Q1 Automotive Grade Linear Thermistor

Get started today with the Thermistor Design Tool, offering complete resistance vs temperature table (RT table) computation, other helpful methods to derive temperature and example C-code. Linear thermistors offer linearity and consistent sensitivity across temperature to enable simple and accurate methods for temperature conversion. Low power consumption .
