BA15218

Standaed ICs Dual high slew rate, low noise operational amplifier BA15218 / BA15218F / BA15218N The BA15218, BA15218F, and BA15218N are monolithic ICs with two built-in low-noise, low-distortion operational amplifiers featuring internal phase compensation. Either a dual or single power supply can be driven, and these products can be driven by a digital system 5V single power supply. The following packages are available: 8-pin DIP (BA15218), 8-pin SOP (BA15218F), and 8-pin SIP (BA15218N). •1)Features Low-voltage operation and single power supply drive enabled. (Single power supply: 4 to 32V, dual power supply: ±3 to ±16V) 2) Low noise level. (Vn = 1.0µVrms typ. : RIAA) 3) High slew rate. (SR = 3V / µs, GBW = 10MHz typ.) 4) Low offset voltage. (VIO = 0.5mV typ.) 5) High gain and low distortion. (GVO = 110dB, THD = 0.0015%) 6) Pin connections are the same as with standard dual operational amplifiers, and outstanding characteristics make these products compatible with the 4558 and 4560 models. •Block diagram BA15218 / BA15218F BA15218N OUT1 1 1ch OUT2 6 – IN2 5 + IN2 + 1ch – + 2ch – 3 4 5 6 7 8 + IN1 VEE + IN2 – IN2 OUT2 VCC 2ch + – 2 + – IN1 VEE 4 7 1 – + IN1 3 VCC OUT1 – IN1 2 8 1 Standaed ICs BA15218 / BA15218F / BA15218N •Internal circuit configuration VCC R1 Q8 Q5 Q18 Q19 Q16 Q17 Q13 Q11 – IN Q9 Q1 Q2 R6 Q10 R5 C2 + IN OTHER CH R7 D1 Q3 R2 C1 Q12 Q6 Q4 R8 Q15 Q14 Q7 R9 R4 R3 VEE OUT •Absolute maximum ratings (Ta = 25°C) Parameter Power supply voltage Symbol VCC Limits BA15218 ± 18 800∗ BA15218F ± 18 550∗ BA15218N ± 18 900∗ Power dissipation Pd Differential input voltage VID ± VCC ± VCC ± VCC V mW V VI – VCC ~ VCC – VCC ~ VCC – VCC ~ VCC V Load current IOMAX ± 50 ± 50 ± 50 mA Operating temperature Topr – 40 ~ + 85 – 40 ~ + 85 – 40 ~ + 85 °C Storage temperature Tstg – 55 ~ + 125 – 55 ~ + 125 – 55 ~ + 125 °C Common-mode input voltage ∗ Refer to Pd characteristics diagram.
