Quad ground sense operational amplifier

Transcription

1 Quad ground sense operational amplifier BAA / BAAF / BAAFV The BAA, BAAF, and BAAFV 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 V 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: ±. to ± 6V) ) Common-mode input voltage can be operated from the ground level. ) Differential input voltage can be operated up to the power supply voltage level. ) Low current dissipation. (IQ =.6mA) ) Low offset voltage and offset current. (VIO = mv, IIO = na typ.) 6) Four operational amplifiers with phase compensation are built into the DIP / SOP Pin. ) Compatible with model operational amplifiers of other manufacturers.
