TMP36 Temperature Sensor

OVERVIEW:

This is the same temperature sensor that is included in our SparkFun Inventor's Kit. The TMP36 is a low voltage, precision centigrade temperature sensor. It provides a voltage output that is linearly proportional to the Celsius temperature. It also doesn't require any external calibration to provide typical accuracies of ±1°C at +25°C and ±2°C over the −40°C to +125°C temperature range. We like it because it's so easy to use: Just give the device a ground and 2.7 to 5.5 VDC and read the voltage on the Vout pin. The output voltage can be converted to temperature easily using the scale factor of 10 mV/°C.

Features:

• Low Voltage Operation (2.7 V to 5.5 V)
• Calibrated Directly in C
• 10 mV/C Scale Factor (20 mV/C on TMP37)
• 2C Accuracy over Temperature (Typ)
• 0.5C Linearity (Typ)
• Stable with Large Capacitive Loads
• Specified –40C to +125C, Operation to +150C
• Less than 50 A Quiescent Current
• Shutdown Current 0.5A Max
• Low Self-Heating
