D1+
1
Diode Current Source
To Diode Anode. Connected to remote discrete
diode-connected transistor junction or to the
diode-connected transistor junction on a remote IC
whose die temperature is being sensed. A 2.2 nF
diode bypass capacitor is recommended to filter high
frequency noise. Place the 2.2 nF capacitor between
and as close as possible to the LM95221’s D+ and
D− pins. Make sure the traces to the 2.2 nF
capacitor are matched. Ground this pin if this
thermal diode is not used.
D1−
2
Diode Return Current Sink
To Diode Cathode. A 2.2 nF capacitor is
recommended between D1+ and D1-. Ground this
pin if this thermal diode is not used.

should be
bypassed with a 0.1 µF capacitor in parallel with 100
pF. The 100 pF capacitor should be placed as close
as possible to the power supply pin. Noise should
be kept below 200 mVp-p, a 10 µF capacitor may be
required to achieve this.
