1 Standard ICs 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. •Applications Active filters Audio amplifiers VCOs Other electronic circuits •Block diagram 1ch 2ch VCC OUT2 – IN2 + IN2 OUT1 – IN1 + IN1 VEE 4 3 2 1 8 7 5 6 + – – 1ch 2ch + – + – BA4558 / BA4558F BA4558N + •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 volt- age. 6) High gain and low noise. |
