V DD should be bypassed with a 0.1µF capacitor in parallel with 100pF. The 100pF capacitor should be placed as close as possible to the power supply pin. A bulk capacitance of approximately 10µF needs to be in the near vicinity to the LM89 V DD. D+ 2 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 required to filter high frequency noise. Place the 2.2 nF capacitor between and as close as possible to the LM89’s D+ and D− pins. Make sure the traces to the 2.2 nF capacitor are matched. D− 3 Diode Return Current Sink To Diode Cathode.
