www.fairchildsemi.com KA224/KA224A, KA324/KA324A, KA2902 Quad Operational Amplifier Features Internally Frequency Compensated for Unity Gain Large DC Voltage Gain: 100dB Wide Power Supply Range: KA224 / KA224A, KA324 / KA324A : 3V~32V (or ±1.5 ~ 16V) KA2902: 3V~26V (or ±1.5V ~ 13V) Input Common Mode Voltage Range Includes Ground Large Output Voltage Swing: 0V to VCC -1.5V Power Drain Suitable for Battery Operation Description The KA324 series 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 1 14-SOP 1 Internal Block Diagram OUT1 1 IN1 (-) 14 OUT4 1 _ + 4 _ 13 IN4 (-) 12 IN4 (+) 11 GND _ + 2 + _ 3 10 IN3 (+) 9 IN3 (-) 8 OUT3 2 IN1 (+) 3 VCC 4 IN2 (+) IN2 (-) OUT2 + 5 6 7 Rev. 1.0.4 ©2002 Fairchild Semiconductor Corporation KA224/KA224A, KA324/KA324A, KA2902 Schematic Diagram (One Section Only) VCC Q5 Q6 Q12 Q17 Q19 Q20 Q2 IN(-) Q1 R2 IN(+) Q11 Q21 Q7 Q8 Q9 Q10 Q13 Q15 Q14 Q16 OUTPUT Q3 Q4 C1 Q18 R1 GND Absolute Maximum Ratings Parameter Power Supply Voltage Differential Input Voltage Input Voltage Outp...
