VALUE
The data format is 13 bits, 0.0625°C per bit. Full-scale allows display up to ±256°C.
RT12–RT0: Remote Temperature Result
Bits 3-15 Shows the remote temperature measurement result.
PVLD Power Valid Flag
Bit 1 This bit is the power valid flag.
The TMP512/13 do not start a temperature conversion if the power supply is not valid. If the voltage is less than
2.7V during a conversion, the PVLD bit is set to '1' and the temperature result may be incorrect.
DO Diode Open Flag
Bit 0 This bit is the diode open flag.
If the Remote Channels are open during a conversion, then Diode Open bit is set at the end of the conversion.
Shunt Positive Limit Register 0Ch (Read/Write)
At full-scale range = ±320mV, 15-bit + sign, LSB = 10μV (decimal = 32000, positive value hex = 7D00, negative
value hex = 8300).
