AMPLIFIER TOPOLOGY  
The topology chosen for the LMC6022 is unconventional  
(compared to general-purpose op amps) in that the tradi-  
tional unity-gain buffer output stage is not used; instead, the  
output is taken directly from the output of the integrator, to al-  
low rail-to-rail output swing. Since the buffer traditionally de-  
livers the power to the load, while maintaining high op amp  
gain and stability, and must withstand shorts to either rail,  
these tasks now fall to the integrator.  
As a result of these demands, the integrator is a compound  
affair with an embedded gain stage that is doubly fed forward  
(via Cf and Cff) by a dedicated unity-gain compensation  
driver. In addition, the output portion of the integrator is a  
push-pull configuration for delivering heavy loads. While  
sinking current the whole amplifier path consists of three  
gain stages with one stage fed forward, whereas while  
sourcing the path contains four gain stages with two fed  
forward.

The large signal voltage gain while sourcing is comparable  
to traditional bipolar op amps for load resistance of at least 5  
k. The gain while sinking is higher than most CMOS op  
amps, due to the additional gain stage; however, when driv-
