APPLICATION INFORMATION The LM358 series is made by using two internally compensated, and two-stage operational amplifiers. The first stage of each consists of differential input devices T2 and T4, with input buffer transistors T1 and T3, and the differential to single ended converter T5 and T6. 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 can be employed, thus saving chip area. The transconductance reduction is accomplished by splitting the collectors of T2 and T4. 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 a standard current source load amplifier stage. 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.
