Temperature Accuracy
Description
Microchip Technology Inc.s MCP9808 digital
temperature sensor converts temperatures between
-20癈 and +100癈 to a digital word with
?.25癈/?.5癈 (typical/maximum) accuracy.
The MCP9808 comes with user-programmable registers
that provide flexibility for temperature sensing
applications. The registers allow user-selectable
settings such as Shutdown or Low-Power modes and
the specification of temperature Alert window limits and
critical output limits. When the temperature changes
beyond the specified boundary limits, the MCP9808
outputs an Alert signal. The user has the option of setting
the Alert output signal polarity as an active-low or active-
high comparator output for thermostat operation, or as a
temperature Alert interrupt output for microprocessor-
based systems. The Alert output can also be configured
as a critical temperature output only.
This sensor has an industry standard 400 kHz, 2-wire,
SMBus/I
2
C compatible serial interface, allowing up to
eight or sixteen sensors to be controlled with a single
serial bus (see Table 3-2 for available Address codes).
These features make the MCP9808 ideal for
sophisticated, multi-zone, temperature-monitoring
applications.
