The extremely low power absorption when there is no load connected to the output, 5.4 uA only, makes the inte
-
grated circuit perfectly suitable for low power or battery powered boards. The board houses on its side a miniature
connector with 1.25 mm pitch for the power supply and the output signal; the PCB has been designed to offer also
2,54mm pitch holes useful to weld on them a pin-strip, to allow the breakout board connection to other boards that
could use the temperature sensor. The power line
is noise filtered by means of C1 ceramic capacitor; The C2 capacitor filters the sensor output signal, introducing so
a minimum delay (just 1 millisecond) between the temperature variation and the following output voltage. On the
power line it has been inserted the LD1 LED which, when is on, indicates if the circuit is powered and active or not.
