Inverter Pulse Response  
differential to single ended converter Q3 and Q4. The first  
stage performs not only the first stage gain function but also  
performs the level shifting and transconductance reduction  
functions. By reducing the transconductance, a smaller  
compensation capacitor (only 5.0 pF) can be employed, thus  
saving chip area. The transconductance reduction is  
accomplished by splitting the collectors of Q24 and Q22.  
Another feature of this input stage is that the input Common  
Mode range can include the negative supply or ground, in  
single supply operation, without saturating either the input  
devices or the differential to single–ended converter. The  
second stage consists of a standard current source load  
amplifier stage.  
The output stage is unique because it allows the output to  
swing to ground in single supply operation and yet does not  
exhibit any crossover distortion in split supply operation. This  
is possible because Class AB operation is utilized.  
Each amplifier is biased from an internal voltage regulator  
which has a low temperature coefficient thus giving each  
amplifier good temperature characteristics as well as  
excellent power supply rejection.

CIRCUIT DESCRIPTION  
The MC3458/3358 is made using two internally  
compensated, two–stage operational amplifiers. The first  
stage of each consists of differential input devices Q24 and  
Q22 with input buffer transistors Q25 and Q21 and the
