... V supply) as the output will saturate long before it reaches the supply rails. Again the AMP04’s topology does not have this limitation. Figure 4 illustrates the AMP04 operating at the same common-mode conditions as in Figure 3. None of the internal nodes has a signal high enough to cause amplifier satu- ration ...

... Driven shields are easily realized with the AMP04. Examination of the simplified schematic shows that the potentials at the gain set resistor pins of the AMP04 follow the inputs precisely. As shown in Figure 5, shield drivers are easily realized by buffering the potential at these pins by a dual, single supply op amp such as the OP213 ...

... Filtering can be applied to reduce wide band noise. Figure OOS shows low-pass filter, gain of 1000 for the AMP04. Fig- ures 7b and 7c illustrate the effect of filtering on noise. The photo in Figure 7b shows the output noise before filtering. By adding a 0.15 F capacitor, the noise is reduced by about a factor shown in Figure 7c ...

... The RTD is excited by a 100 A constant current that is regulated by amplifier A (OP295). The 0.202 volts reference voltage used to generate the constant cur- rent is divided down from the 2.500 volt reference. The AMP04 amplifies the bridge output mV/ C output coefficient. R3 ...

... NULL adjusted first, followed by SPAN adjust. The entire circuit can be remotely placed, and powered from the 4-20 mA 2-wire loop. 4-20 mA Loop Receiver At the receiving end of a 4-20 mA loop, the AMP04 makes a convenient differential receiver to convert the current back to a usable voltage (Figure 13). The 4-20 mA signal current passes through a 100 sense resistor ...
