| Standard ICs Quad ground sense operational amplifier BA10324A / BA10324AF / BA10324AFV The BA10324A, BA10324AF, and BA10324AFV are monolithic ICs with four built-in operational amplifiers featuring internal phase compensation. Either a dual or single power supply can be driven, and these products can be driven by a digital system 5V single power supply. These products can be used in a wide range of administrative and industrial applications, including transducer amplifiers and DC amplifiers. *Applications type pre-amplifiers Ground sensing Active filters DC amplifiers Pulse generators. *Features of operating power supply voltages and 1) Wide range single power supply drive enabled. (single power supply: 3 to 32V, dual power supply: 1.5 to 16V) 2) Common-mode input voltage can be operated from the ground level. 3) Differential input voltage can be operated up to the power supply voltage level. 4) Low current dissipation. (IQ = 0.6mA) 5) Low offset voltage and offset current. (VIO = 2mV, IIO = 5nA typ.) 6) Four operational amplifiers with phase compensation are built into the DIP / SOP Pin 14. 7) Compatible with model 324 operational amplifiers of other manufacturers. *Block diagram BA10324A / BA10324AF / BA10324AFV OUT1 - IN1 + IN1 VCC + IN2 - IN2 OUT2 1 2 3 4 5 -+ +- 14 1 -+ OUT4 - IN4 + IN4 VEE + IN3 - IN3 OUT3 4 +- 13 12 11 10 6 7 2 3 9 8 1 Standard ICs BA10324A / BA10324AF / BA10324AFV *Internal circuit configuration VCC - IN + IN OUT VEE *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 BA10324A 32 ( 16) 950 VCC - 0.3 ~ VCC - 40 ~ + 85 - 55 ~ + 125 BA10324AF BA10324AFV 32 ( 16) 450 VCC - 0.3 ~ VCC - 40 ~ + 85 - 55 ~ + 125 32 ( 16) 400 VCC - 0.3 ~ VCC - 40 ~ + 85 - 55 ~ + 125 Unit V mW V V C C Refer to the Pd characteristics diagram.
