| 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 ~ 15V) 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 Rev. 1.0.1 (c)2001 Fairchild Semiconductor Corporation KA224/KA224A, KA324/KA324A, KA2902 Schematic Diagram (One Section Only) Absolute Maximum Ratings Parameter Power Supply Voltage Differential Input Voltage Input Voltage Output Short Circuit to GND Vcc15V, TA=25C(one Amp) Power Dissipation Operating Temperature Range Storage Temperature Range Symbol KA224/KA224A VCC VI(DIFF) VI PD TOPR TSTG 16 or 32 32 -0.3 to +32 Continuous 570 -25 ~ +85 -65 ~ +150 KA324/KA324A 16 or 32 32 -0.3 to +32 Continuous 570 0 ~ +70 -65 ~ +150 KA2902 13 or 26 26 -0.3 to +26 Continuous 570 -40 ~ +85 -65 ~ +150 Unit V V V mW C C 2 KA224/KA224A, KA324/KA324A, KA2902 Electrical Characteristics (VCC=5.0V, VEE=GND, TA=25 C, unless otherwise specified) Parameter Symbol Conditions KA224 KA324 Max.
