negative input exceeds that in the positive input, stray  
capacitance from the output will create a net negative feed-  
back and improve the circuit stability. If the impedance in  
the positive input is greater, the feedback due to stray  
capacitance will be positive and instability may result. The  
degree of positive feedback depends upon source impedance  
imbalance, operating gain, and board layout. The addition of  
a small bypass capacitor of 5pF to 50pF directly between the  
inputs of the IA will generally eliminate any positive feed-  
back. CMR errors due to the input impedance mismatch will  
also be reduced by the capacitor.  
Another distinct advantage of the INA110 is the high fre-  
quency CMR response. High frequency noise and sharp  
common-mode transients will be rejected. To preserve AC  
CMR, be sure to minimize stray capacitance on the input  
lines. Matching the RCs in the two inputs will help to  
maintain high AC CMR.  
APPLICATIONS  
In addition to general purpose uses, the INA110 is designed  
to accurately handle two important and demanding applica-  
tions: (1) inputs with high source impedances such as  
capacitance/crystal/photodetector sensors and low-pass  
filters and series-input protection devices, and (2) rapid-  
scanning data acquisition systems requiring fast settling  
time. Because the user has access to the output sense, current  
sources can also be constructed using a minimum of external  
components. Figures 6 through 19 show application circuits.  
The INA110 is designed for fast settling with easy gain  
selection. It has especially excellent settling in high gain. It  
can also be used in fast-settling unity-gain applications. As  
with all such amplifiers, the INA110 does exhibit significant  
gain peaking when set to a gain of 1. It is, however,  
unconditionally stable. The gain peaking can be cancelled  
by band-limiting the negative input to 400kHz with a simple  
external RC circuit for applications requiring flat response.  
CMR is not affected by the addition of the 400kHz RC in a  
gain of 1.
