FUNCTION

TYPICAL CONNECTION

NUMBER

VDD

Positive Supply Voltage Input

DC Voltage from 3.0 V to 3.6 V. VDD 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 VDD.

D+

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.

Diode Return Current Sink

To Diode Cathode.
