Amplifier characteristics

 

 
In  the  following  pages,  several  amplifier 
characteristics are shown: 
- Frequency response (Fig. 3, 4) 
- Square wave response (Fig. 5, 6, 7) 

- Slew rate (Fig. 8) 
-  Capacitive  load  dependency  of  square 
wave output (Fig. 9) 
- Triangle and sine response (Fig. 10, 11) 
- Noise and offset (Fig. 12) 
- Input to output delay time (Fig. 13)
