LM35DZ Sensor IC Precision Temperature Sensor with 10mV/°C Output 4V to 30V Supply and 0°C to 100°C Range

The LM35DZ is a precision integrated-circuit temperature sensor with an output voltage linearly proportional to Centigrade temperature. Unlike Kelvin-calibrated sensors, the LM35 eliminates the need to subtract a large constant voltage from the output, providing convenient Centigrade scaling directly. The device requires no external calibration or trimming and delivers typical accuracies of ±¼°C at room temperature and ±¾°C across the full −55°C to 150°C temperature range.
