产品概览
The TMP36GT9Z from Analog Devices is a low-voltage, precision centigrade temperature sensor in a 3-lead TO-92 package. It provides an analog output voltage linearly proportional to Celsius temperature with a scale factor of 10 mV/°C and a 750 mV offset at 25°C. Rated from -40°C to +125°C with ±2°C typical accuracy, it operates from a single 2.7 V to 5.5 V supply with under 50 µA quiescent current.
