Basic capability
– 0 = Alarm and critical trips turned OFF.
– 1 = Alarm and critical trips turned ON.
Accuracy
– 0 = Accuracy ±2°C over the active range and ±3°C over the monitoring range
– 1 = High accuracy ±1°C over the active range and ±2°C over the monitoring range
Range width
– 0 = Values lower than 0°C will be clamped and represented as binary value '0'.
– 1 = Temperatures below 0°C can be read and the Sign bit will be set accordingly.
Temperature resolution
– 01 = This 10-bit value is fixed for STTS424, providing temperatures at 0.25°C resolution
(V
– 1 = STTS424 supports a voltage up to 10 volts on the A0 pin (default).
