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

•

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.

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.

8) Low input bias current of 10nA (typ.).

9) Each package contains two operational amplifiers.

10) Internal phase compensation provided.

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
