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 •Ground sensing type pre-amplifiers Active filters DC amplifiers Pulse generators. •1)Features Wide range of operating power supply voltages and 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 1 – IN1 2 1 4 – + + – 14 OUT4 13 – IN4 + IN1 3 12 + IN4 VCC 4 11 VEE + IN2 5 10 + IN3 9 – IN3 8 OUT3 – IN2 6 OUT2 7 – + + – 2 3 1 Standard ICs BA10324A / BA10324AF / BA10324AFV •Internal circuit configuration VCC – IN OUT + IN VEE •Absolute maximum ratings (Ta = 25°C) Parameter Symbol Limits BA10324A BA10324AF BA10324AFV Unit Power supply voltage VCC 32 ( ± 16) 32 ( ± 16) 32 ( ± 16) V Power dissipation Pd 950∗ 450∗ 400∗ mW Differential input voltage VID ± VCC ± VCC ± VCC V Common-mode input voltage VI – 0.3 ~ VCC – 0.3 ~ VCC – 0.3 ~ VCC V Operating temperature Topr – 40 ~ + 85 – 40 ~ + 85 – 40 ~ + 85 °C Storage temperature Tstg – 55 ~ + 125 – 55 ~ + 125 – 55 ~ + 125 °C ∗ Refer to the Pd characteristics diagram.
