TC1047 series( TC1047, TC1047A )
General description
The TC1047 and TC1047A are linear voltage output temperature sensors whose output voltage is directly proportional to the measured temperature. The TC1047 and TC1047A can accurately measure temperature from -40°C to +125°C. With the TC1047, the supply voltage can vary between 2.7V and 4.4V. The power supply range of the TC1047A is from 2.5V to 5.5V.
The output voltage range for these devices is typically 100 mV at -40°C, 500 mV at 0°C, 750 mV at +25°C and 1.75V at +125°C. A 10 mV/°C voltage slope output response allows for a predictable temperature measurement over a wide temperature range. The TC1047 and TC1047A are packaged in 3-pin SOT-23B packages, making them ideal for space-critical applications.

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.
