FUNCTIONAL DESCRIPTION
The MCP9808 temperature sensors consist of a band-
gap-type temperature sensor, a Delta-Sigma Analog-to-
Digital   Converter   (敚   ADC),   user-programmable
registers and a 2-wire SMBus/I
2
C protocol compatible
serial interface. Figure 5-1 shows a block diagram of the
register structure.
