TMP37GS Frequently Asked Questions (FAQs)
-
The TMP37GS should be placed as close as possible to the thermal source being measured, with minimal thermal resistance between the device and the source. The device should be oriented to minimize thermal gradients and air currents. A recommended layout is to place the device on a solid copper pour or a thermal pad, with minimal routing and vias underneath.
-
The TMP37GS output voltage is proportional to the absolute temperature, not the supply voltage. To handle this, use a voltage reference or a stable voltage source for the supply, and consider using an analog-to-digital converter (ADC) with a high input impedance to minimize loading effects.
-
Self-heating can cause errors in temperature measurement. To minimize self-heating, use a low current excitation (e.g., 10-20 μA), keep the device away from high-power components, and ensure good thermal conduction to the surrounding environment. You can also consider using a thermally conductive material or a heat sink to dissipate heat.
-
Calibration involves trimming the device's offset and gain errors. You can use a precision temperature reference and a calibration routine to adjust the output voltage to match the desired temperature reading. Analog Devices provides a calibration procedure in the datasheet, or you can use a third-party calibration service.
-
The TMP37GS is specified to operate from -40°C to +150°C, but accuracy degrades at extreme temperatures. For highest accuracy, operate the device between 0°C and 100°C. Outside this range, the device may still provide usable readings, but with reduced accuracy.
