function of the accuracy of the matching and is further  
enhanced by the use of negative feedback in the input stage.  
Advanced laser trimming techniques are used to further  
compensate for residual matching errors.  
lower bias currents (50pA) and overvoltage protection. The  
+IR and –IR inputs have a 10ms pulse rating of 6000V  
differential and 3000V common-mode (see Definitions for a  
discussion of common-mode and isolation-mode voltages.)  
The addition of the buffer amplifiers also creates a voltage-  
in voltage-out transfer function with the gain set by RG1 and  
A model of the 3650 suitable for simple circuit analysis is  
shown in Figure 3. The output is a current dependent voltage  
source, VD, whose value depends on the input current. Thus,  
the 3650 is a transconductance amplifier with a gain of one  
volt per microamp. When voltage sources are used, the input  
current is derived by using gain setting resistors in series  
with the voltage source (see Installation and Operating  
Instructions for details). RIN is the differential input imped-  
ance. The common-mode and isolation impedances are very  
high and are assumed to be infinite for this model.

OPERATING INSTRUCTIONS  
POWER SUPPLY CONNECTIONS  
The power supply connections for the 3650 and 3652 are  
shown in Figure 5. When a DC/DC converter is used for  
isolated power, it is placed in parallel with the isolation  
barrier of the amplifier. This can lower the isolation imped-  
ance and degrade the isolation-mode rejection of the overall  
circuit. Therefore, a high quality, low leakage DC/DC con-  
verter such as the Burr-Brown Model 722 should be used.

The offset nulling circuits are identical for the 3650 and  
3652 and are shown in Figure 5. The offset adjust circuitry  
is optional and the units will meet the stated specifications  
with the BAL terminals unconnected. Provisions are avail-  
able to null both the input and output stage offsets. If the  
amplifier is operated at a fixed gain, normally only one  
adjustment will be used: the output stage (10kΩ adjustment)  
for low gains and the input stage (50kΩ adjustment) for high  
gains, (>10).

Use the following procedure if it is desired to null both input  
and output components. (For example, if the gain of the  
amplifier is to be switched). The input stage offset is first  
nulled (50kΩ adjustment) with the appropriate input signal  
pins connected to input common and the amplifier set at its  
maximum gain. The gain is then set to its minimum value  
and the output offset is nulled (10kΩ adjustment).  
FIGURE 3. Simple Model of 3650.  
A simplified model of the 3652 is shown in Figure 4. The  
isolation and output stages are identical to the 3650. Addi-  
tional input circuitry consisting of FET buffer amplifiers and  
input protection resistors have been added to give higher  
differential and common-mode input impedance (1011Ω),  
Same as 3650 in Figure 3.
