ANALOG TEMPERATURE SENSOR BOARD
MM111
In addition to the analog sensor, the breakout is based on
MCP6L01T-E / LT operational amplifier by Microchip. The
sensor is able to ensure a linear correlation between tem-
perature and output voltage and has a measuring accuracy
of 0.4 ° C only. The voltage output varies according to the
temperature measured by following a linear constant value
of typically 21 mV / ° C, starting from a maximum of 5 V at
-50 ° C. At a temperature of zero Celsius degrees the output
voltage is slightly higher than 1 volt.
Table 1 shows the typical output voltage values for the dif-
ferent temperatures. The component can operate with really
low input power supply voltages (from 1.5V to 5.5 volts) and
in a wide temperature range (-50 to 150 ° C).
