The BA4558, BA4558F, and BA4558N are monolithic ICs with two operational amplifiers featuring low power consumption 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 amplifier. The BA4558F comes in an 8-pin SOP package, and the BA4558N in an 8-pin SIP package.

FEATUREs
1) Low power dissipation of approximately 50mW (typ.).
2) Built-in output short-circuit protection circuit.
3) Internal phase compensation.
4) No latch-up.
5) Wide range of common mode and differential voltage.
6) High gain and low noise.
