General Description
BA728 General Description
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.

BA728 Features
Can be driven from a single power supply.
Low power.
Pin layout is the same as that of the generalpurpose 4558 operational amplifier.
When driven from a single power supply, the power supply voltage ranges from 3 to 18V.
When driven from a dual power supply, the power supply voltage ranges from ± 1.5 to ± 9V.
Output is protected against short-circuits.
Output block is operated as a class AB to minimize crossover distortion.
Low input bias current of 10nA (typ.).
Each package contains two operational amplifiers.
Internal phase compensation provided.
BA728 Typical Application
Ground sensing small-signal amplifiers
Control amplifiers requiring high phase margin, such as motor drivers
Amplifiers operated on low voltages
Capacitive loaded amplifiers
Control amplifiers requiring high phase margin, such as motor drivers
