Standard ICs
Dual operational amplifier
BA728 / BA728F / BA728N
The BA728, BA728F, and BA728N are ICs with two independently functioning operational amplifiers featuring inter-
nal 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 general-
purpose 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 mini-
mize crossover distortion.
8) Low input bias current of 10nA (typ.).
9) Each package contains two operational amplifiers.
10) Internal phase compensation provided.
