Manufacturer: ROHM Semiconductor


BA4558 datasheet




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 haracteristics 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.
