The KA258 series consist of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltage. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power Supply voltage. 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. 8-DIP 1 8-SOP 1 9-SIP 1 Internal Block Diagram Rev. 1.0.1 (c)2001 Fairchild Semiconductor Corporation KA258/KA258A, KA358/KA358A, KA2904 Schematic Diagram (One section only) GND Absolute Maximum Ratings Parameter Symbol KA258/KA258A KA358/KA358A KA2904 Unit VCC 16 or 32 16 or 32 13 or 26 V VI(DIFF) 32 32 26 V Input Voltage VI -0.3 to +32 -0.3 to +32 -0.3 to +26 V Output Short Circuit to GND VCC15V, TA = 25 C(One Amp) - Continuous Continuous Continuous - Supply Voltage Differential Input Voltage 2 Operating Temperature Range TOPR -25 ~ + 85 0 ~ + 70 -40 ~ + 85 C Storage Temperature Range TSTG -65 ~ + 150 -65 ~ + 150 -65 ~ + 150 C KA258/KA258A, KA358/KA358A, KA2904 Electrical Characteristics (Vcc = 5.0V, VEE = GND, T = 25 C, unless otherwise specified) KA258 KA358 Parameter Symbol Conditions Input Offset Voltage VIO VCM = 0V to VCC -1.5V VO(P) = 1.4V, RS = 0 - 2.9 5.0 Input Offset Current IIO - - 3 Input Bias Current IBIAS - - Input Voltage Range VI(R) VCC = 30V (KA2904, VCC = 26V) Supply Current Large Signal Voltage Gain Output Voltage Swing ICC GV VO(H) VO(L) KA2904 Typ Max.
