1.3 Block Diagram
The functional blocks of this device are shown below:
Figure 3 :
Functional Blocks of AS621x
In Figure 3 the functional blocks are depicted. The sensing element for sensing the temperature is a Si
bipolar transistor. The analog signal of the sensing element is converted into a digital signal by the A/D
converter and the signal is further processed by a digital signal processor and written into the
registers. The registers can be accessed via the serial bus interface (I²C bus).
