AMP04  
4-20 mA Loop Receiver  
Single Supply Programmable Gain Instrumentation Amplifier  
Combining with the single supply ADG221 quad analog switch,  
the AMP04 makes a useful programmable gain amplifier that  
can handle input and output signals at zero volts. Figure 15  
shows the implementation. A logic low input to any of the gain  
control ports will cause the gain to change by shorting a gain-  
set resistor across AMP04’s Pins 1 and 8. Trimming is required  
at higher gains to improve accuracy because the switch ON-  
resistance becomes a more significant part of the gain-set  
resistance. The gain of 500 setting has two switches connected  
in parallel to reduce the switch resistance.  
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 Ω sense resistor. The voltage drop is differentially  
amplified by the AMP04. The 4 mA offset is removed by the  
offset correction circuit.

Figure 14 shows a 350 Ω load cell that is pulsed with a low duty  
cycle to conserve power. The OP295’s rail-to-rail output capa-  
bility allows a maximum voltage of 10 volts to be applied to the  
bridge. The bridge voltage is selectively pulsed on when a mea-  
surement is made. A negative-going pulse lasting 200 ms should  
be applied to the MEASURE input. The long pulsewidth is  
necessary to allow ample settling time for the long time constant  
of the low-pass filter around the AMP04. A much faster settling  
time can be achieved by omitting the filter capacitor.

The switch ON resistance is lower if the supply voltage is 12 volts  
or higher. Additionally, the overall amplifier’s temperature coeffi-
