| Standard ICs Quad operational amplifier BA14741 / BA14741F The BA14741 and BA14741F are monolithic ICs with four operational amplifiers featuring internal phase compensation mounted on a single silicon chip. Either a dual or single power supply can be driven. *Applications Active filters Audio amplifiers VCOs Other electronic circuits *Featuresphase compensation circuit. 1) Built-in 2) Wide range of operating power supply voltages. ( 2 to 18V) 3) Can be connected to other standard quad operational amplifiers. 4) High gain and low noise. 5) Compatible with model 741 operation amplifiers of other manufacturers. *Block diagram BA14741 / BA14741F OUT1 - IN1 + IN1 VCC + IN2 - IN2 OUT2 1 1ch 2 3 4 5 6 2ch 7 -+ +- 3ch 8 OUT3 -+ +- 4ch 13 - IN4 12 + IN4 11 VEE 10 + IN3 9 - IN3 14 OUT4 1 Standard ICs BA14741 / BA14741F *Internal circuit configuration VCC - IN OUT + IN VEE [SUB] *Absolute maximum ratings (Ta = 25C) Parameter Power supply voltage Power dissipation Differential input voltage Common-mode input voltage Operating temperature Storage temperature Symbol VCC Pd VID VI Topr Tstg Limits BA14741 36 ( 18) 950 VCC - VCC ~ VCC - 40 ~ + 85 BA14741F 36 ( 18) 450 VCC - VCC ~ VCC - 40 ~ + 85 Unit V mW V V C C - 55 ~ + 125 - 55 ~ + 125 Refer to Pd characteristics diagram.
