The LM75BD.118 is a precision digital temperature sensor manufactured by NXP. It measures temperatures from -55°C to +125°C and provides a digital output via its I2C/SMBus-compatible interface. It features a ±2°C accuracy over an extended temperature range and is a small package size. The output value is determined by a comparison of the internal temperature-sensing element to an external reference voltage. The LM75BD.118 includes integrated over and under temperature alarm functions, allowing overtemperature conditions to be reported.
