the thermocouple and should be placed as close as possible to  
the two terminating junctions. With the thermocouple measuring  
tip immersed in a 0°C ice bath, R6 should be adjusted until the  
output is at 0 V.  
Figure 68 shows the low-side monitor equivalent. In this circuit,  
the input common-mode voltage to the AD8572 is at or near  
ground. Again, a 0.1 Ω resistor provides a voltage drop propor-  
tional to the return current. The output voltage is given as

Using the values shown in Figure 66, the output voltage tracks  
temperature at 10 mV/°C. For a wider range of temperature  
measurement, R9 can be decreased to 62 kΩ. This creates a  
5 mV/°C change at the output, allowing measurements of up to  
1000°C.

Because of its low input bias current and superb offset voltage at  
single-supply voltages, the AD857x is an excellent amplifier for  
precision current monitoring. Its rail-to-rail input allows the  
amplifier to be used as either a high-side or a low-side current  
monitor. Using both amplifiers in the AD8572 provides a simple  
method to monitor both current supply and return paths for  
load or fault detection.

Figure 67 shows a high-side current monitor configuration.  
Here, the input common-mode voltage of the amplifier is at or  
near the positive supply voltage. The rail-to-rail input of the  
amplifier provides a precise measurement, even with the input  
common-mode voltage at the supply voltage. The CMOS input  
structure does not draw any input bias current, ensuring a  
minimum of measurement error.

PRECISION VOLTAGE COMPARATOR  
The AD857x can be operated open-loop and used as a precision  
comparator. The AD857x has less than 50 μV of offset voltage  
when run in this configuration. The slight increase of offset  
voltage stems from the fact that the autocorrection architecture  
operates with lowest offset in a closed-loop configuration, that  
is, one with negative feedback. With 50 mV of overdrive, the  
device has a propagation delay of 15 μs on the rising edge and  
8 μs on the falling edge.  
The 0.1 Ω resistor creates a voltage drop to the noninverting  
input of the AD857x. The output of the amplifier is corrected  
until this voltage appears at the inverting input. This creates a  
current through R1 that in turn flows through R2. The monitor  
output is given by  
Care should be taken to ensure the maximum differential  
voltage of the device is not exceeded. For more information,  
refer to the Input Overvoltage Protection section.
