Local resolution is 11 bits; the remote channel resolves at 8 bits, which is coarser but sufficient for tracking a processor die or power-stage hotspot without flooding the bus with data. The part includes a programmable limit register that can trigger an alert when either channel exceeds a set threshold, plus a one-shot mode for on-demand reads that saves bus traffic in a polling loop.
That ±2°C local figure is tight enough for thermal-throttling decisions in a server or industrial controller — a CPU or FPGA will hit its thermal ceiling before the sensor error becomes the dominant term. The ±3°C remote tolerance means this sensor is a good fit for monitoring a hot spot (MOSFET bank, VRM inductor) where the absolute temperature matters less than the trend and the trip point has a few degrees of margin.
