Overview
The LM324/LM324A, LM2902/LM2902A consist of four independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide voltage range. operation from split power supplies is also possible so long as the difference between the two supplies is 3 volts to 32 volts. Application areas include transducer amplifier, DC gain blocks and all the conventional OP Amp circuits which now can be easily implemented in single power supply systems. 14-DIP Internal Block Diagram 1 14-SOP 1 OUT1 1 IN1 (-) 2 IN1 (+) 3 VCC 4 IN2 (+) 5 IN2 (-) 6 OUT2 7 1 _+ _+ 2 4 +_ +_ 3 14 OUT4 13 IN4 (-) 12 IN4 (+) 11 GND 10 IN3 (+) 9 IN3 (-) 8 OUT3 ©2012 Fairchild Semiconductor Corporation LM324/LM324A, LM2902/LM2902A Schematic Diagram (One Section Only) VCC Q5 Q6 Q12 Q17 Q19 GND IN(-) IN(+) Q2 Q1 Q3 Q4 Q7 Q8 Q9 C1 Q11 Q10 Q13 Q20 R1 Q18 Q15 Q14 Q16 R2 OUTPUT Q21.
