Dual operational amplifier

BA4558 / BA4558F / BA4558N

The BA4558, BA4558F, and BA4558N are monolithic ICs with two operational amplifiers featuring low power con-

sumption and internal phase compensation mounted on a single silicon chip. These products offer high speed, a

wide band width, and low noise.

Outstanding thermal characteristics and voltage gain band width make these ICs ideal for use in a wide variety of

electronic circuits. The BA4558 comes in an 8-pin DIP package and is compatible with the 4558 operational amplifi-

er. The BA4558F comes in an 8-pin SOP package, and the BA4558N in an 8-pin SIP package.
