1 The CO4 is monolithic IC 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. Features ) Wide range of operating power supply voltages and single power supply drive enabled. (single power supply: to V, dual power supply: ±.5 to ± 5V) ) Common-mode input voltage can be operated from the ground level. ) Differential input voltage can be operated up to the power supply voltage level. 4) Low current dissipation. (IQ =.6mA) 5) Low offset voltage and offset current. (VIO = mv, IIO = 5nA typ.) 6) Four operational amplifiers with phase compensation are built into the DIP / SOP Pin 4. 7) Compatible with model 4 operational amplifiers of other manufacturers.
