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-SOIC 1 Internal Block Diagram OUT1 1 IN1 (-) 2 IN1 (+) 3 GND 4 8 7 OUT2 + VCC - 6 IN2 (-) + 5 IN2 (+) Rev. 1.0.4 ©2011 Fairchild Semiconductor Corporation KA258/KA258A, KA358/KA358A, KA2904 Schematic Diagram (One section only) VCC Q5 Q12 Q6 Q17 Q19 Q20 Q2 Q3 R1 C1 Q4 IN(-) Q18 Q1 R2 IN(+) Q11 OUTPUT Q21 Q15 Q10 Q7 Q13 Q8 Q14 Q9 Q16 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 VCC≤15V, TA = 25°C(One Amp) - Continuous Continuous Continuous - TOPR -25 ~ +85 0 ~ +70 -40 ~ +85 °C +150 +150 +150 °C -65 ~ +150 -65 ~ +150 -65 ~ +150 °C Supply Voltage Differential Input Voltage Operating Temperature Range Maximum Junction Temperature TJ(MAX) Storage Temperature Range 2 TSTG KA258/KA258A, KA358/KA358A, KA2904 Electrical Characteristics (VCC = 5.0V, VEE = GND, TA = 25°C, unless otherwise specified) KA258 KA358 KA2904 Parameter Symbol Conditions Input Offset Voltage VIO VCM = 0V to VCC -1.5V VO(P) = 1.4V, RS = 0Ω - 2.9 5.0 - 2.9 7.0 - 2.9 7.0 mV Input Offset Current IIO - - 3 30 - 5 50 - 5 50 nA Input Bias Current IBIAS - - 45 150 - 45 250 - 45 250 nA Input Voltage Range VI(R) VCC = 30V (KA2904, VCC = 26V) 0 - VCC -1.5 0 - VCC -1.5 0 - VCC -1.5 V RL = ∞, VCC = 30V (KA2904, VCC = 26V) - 0.8 2.0 - 0.8 2.0 - 0.8 2.0 mA RL = ∞, VCC = 5V - 0.5 1.2 - 0.5 1.2 - 0.5 1.2 mA 50 100 - 25 100 - 25 100 - V/mV 26 - - 26 - - 22 - - V 27 28 - 27 28 - 23 24 - V - 5 20 - 5 20 5 20 mV Supply Current ICC Large Signal Voltage Gain GV Output Voltage Swing VO(H) VO(L) VCC = 15V, RL = 2kΩ VO(P) = 1V to 11V VCC = 30V RL = 2kΩ (VCC = 26V for KA2904) RL = 10kΩ VCC = 5V, RL = 10kΩ Min.
