ADM1032  
Thermocouple effects should not be a major problem as 1°C  
corresponds to about 200 ␮V, and thermocouple voltages are  
about 3 ␮V/°C of temperature difference. Unless there are two  
thermocouples with a big temperature differential between them,  
thermocouple voltages should be much less than 200 ␮V.  
Because the measurement technique uses switched current  
sources, excessive cable and/or filter capacitance can affect the  
measurement. When using long cables, the filter capacitor may  
be reduced or removed.  
Cable resistance can also introduce errors. 1 Ω series resistance  
introduces about 1°C error.  
5. Place a 0.1 µF bypass capacitor close to the VDD pin. In very  
noisy environments place a 2200 pF input filter capacitors  
across D+, D– close to the ADM1032.  
APPLICATION CIRCUIT  
Figure 7 shows a typical application circuit for the ADM1032,  
using a discrete sensor transistor connected via a shielded,  
twisted pair cable. The pull-ups on SCLK, SDATA, and ALERT  
are required only if they are not already provided elsewhere  
6. If the distance to the remote sensor is more than 8 inches, the  
use of twisted pair cable is recommended. This will work up  
to about 6 to 12 feet.  
7. For really long distances (up to 100 feet) use shielded twisted  
pair such as Belden #8451 microphone cable. Connect the  
twisted pair to D+ and D– and the shield to GND close to  
the ADM1032. Leave the remote end of the shield unconnected  
to avoid ground loops.  
i
n the system.  
The SCLK, and SDATA pins of the ADM1032 can be inter-  
faced directly to the SMBus of an I/O controller such as the  
Intel 820 chipset.
