BA728F

Standard ICs Dual operational amplifier BA728 / BA728F / BA728N The BA728, BA728F, and BA728N are ICs with two independently functioning operational amplifiers featuring internal phase compensation. These products offer a wide range of operating voltages, from 3 to 18V ( ± 1.5 to 9V) and are high-performance operational amplifiers which can be driven from a single power supply within the in-phase mode input range, including a negative power supply. Applications Ground sensing small-signal amplifiers Control amplifiers requiring high phase margin, such as motor drivers Amplifiers operated on low voltages Capacitive loaded amplifiers Features 1) Can be driven from a single power supply. 2) Low power. 3) Pin layout is the same as that of the generalpurpose 4558 operational amplifier. 4) When driven from a single power supply, the power supply voltage ranges from 3 to 18V. 5) When driven from a dual power supply, the power supply voltage ranges from ± 1.5 to ± 9V. 6) Output is protected against short-circuits. 7) Output block is operated as a class AB to minimize crossover distortion. 8) Low input bias current of 10nA (typ.). 9) Each package contains two operational amplifiers. 10) Internal phase compensation provided.
