BA4558N

Standard ICs Dual operational amplifier BA4558 / BA4558F / BA4558N 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. •Applications Active filters Audio amplifiers VCOs Other electronic circuits •Features dissipation of approximately 50mW 1) Low power (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. •Block diagram BA4558 / BA4558F BA4558N OUT1 1 8 VCC – IN1 2 – 1ch 7 OUT2 1ch + – + 2ch – + 2ch + IN1 3 + – 6 – IN2 1 2 3 4 5 6 7 OUT2 8 VCC – IN1 OUT1 + IN1 VEE 4 5 + IN2 + IN2 – IN2 VEE 1 Standard ICs BA4558 / BA4558F / BA4558N •Internal circuit configuration VCC R1 Q7 Q5 Q13 Q11 Q8 R6 Q9 R5 + IN Q12 Q6 Q3 Q4 Q10 Q14 OUT R7 R8 Q15 – IN Q1 Q2 R2 VEE R3 R9 R4 D •Absolute maximum ratings (Ta = 25°C) Parameter Power supply voltage Power dissipation Differential input voltage Common-mode input voltage Operating temperature Storage temperature Symbol VCC Pd VID VI Topr Tstg Limits BA4558 ± 18 800∗ ± 30 ± 15 – 40 ~ + 85 BA4558F ± 18 550∗ ± 30 ± 15 – 40 ~ + 85 BA4558N ± 18 900∗ ± 30 ± 15 – 40 ~ + 85 Unit V mW V V °C °C – 55 ~ + 125 – 55 ~ + 125 – 55 ~ + 125 ∗ Refer to Pd characteristics diagram.
