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.
