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.
