TMP9A00-EP
General description
The TMP9A00-EP device is a CMOS, precision analog output temperature sensor available in a tiny 5-pin SC70 package. The TMP9A00-EP operates from –55 °C to 150 °C on a supply voltage of 1.8 V to 5.5 V with a supply current of 4 µA. Operation as low as 1.8 V is possible for temperatures between 15 °C and 150 °C. The linear transfer function has a slope of –11.77 mV/°C (typical) and an output voltage of 1.8639 V (typical) at 0 °C. The TMP9A00-EP has a ±2.5 °C accuracy a from –55 °C to 130 °C and ±3.5 °C from 130 °C to 150 °C.
The 4-µA (maximum) supply current of the TMP9A00-EP limits self-heating of the device to less than 0.01 °C. When V+ is less than 0.5 V, the device is in shutdown mode and consumes less than 20 nA (typical).
The TMP9A00-EP is available in a 5-pin SC70 package that reduces the overall required board space.

eCMD_READ
Feature :
Command that reads the AD conversion value, converts the AD conversion value to a characteristic Temperature, and stores the Temperature in rlt.
Process :
1. Read AD conversion value.
2. Convert AD conversion value to Temperature.
Voltage value = (AD conversion value × VDD) / ( 2AD bit )
Temperature = ((voltage value – voltage offset value) / gain) + Temperature offset value (Min, Max Limit)
3. Store Temperature to rlt.

NOTE :
Please execute this API function after starting AD conversion.
Arduino, Mbeb, ModusToolbox not supported.
eCMD_START_READ
Feature :
Command that starts AD conversion, waits for AD conversion to finish, reads out the AD conversion value, converts the AD conversion value to a characteristic Temperature, and stores the Temperature in rlt.
Process :
1. AD conversion start.
2. Wait until AD conversion is completed.
3. Read AD conversion value.
4. Convert AD conversion value to Temperature.
Voltage value = (AD conversion value × VDD) / ( 2AD bit )
Temperature = ((voltage value – voltage offset value) / gain) + Temperature offset value (Min, Max Limit)
5. Store Temperature to rlt.
