| 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). *Features operation and single power supply drive 1) Low-voltage enabled. (Single power supply: 4 to 32V, dual power supply: 3 to 16V) 2) Low noise level. (Vn = 1.0Vrms typ. : RIAA) 3) High slew rate. (SR = 3V / s, 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 8 VCC + 1ch - + 2ch - - IN1 2 - + IN1 3 1ch + 2ch + - 7 OUT2 6 - IN2 1 2 3 4 5 6 7 OUT2 OUT1 + IN1 + IN2 - IN1 - IN2 VCC VEE VEE 4 5 + IN2 8 1 Standaed ICs BA15218 / BA15218F / BA15218N *Internal circuit configuration VCC R1 Q5 Q8 Q11 - IN Q1 Q2 Q10 + IN C2 R5 R7 D1 Q3 C1 Q4 R8 Q14 Q15 R9 OTHER CH Q9 R6 Q13 Q18 Q19 Q16 Q17 Q6 Q7 R4 Q12 R2 VEE R3 OUT *Absolute maximum ratings (Ta = 25C) Parameter Power supply voltage Power dissipation Differential input voltage Common-mode input voltage Load current Operating temperature Storage temperature Symbol VCC Pd VID VI IOMAX Topr Tstg Limits BA15218 18 800 VCC - VCC ~ VCC 50 - 40 ~ + 85 - 55 ~ + 125 BA15218F 18 550 VCC - VCC ~ VCC 50 - 40 ~ + 85 - 55 ~ + 125 BA15218N 18 900 VCC - VCC ~ VCC 50 - 40 ~ + 85 - 55 ~ + 125 Unit V mW V V mA C C Refer to Pd characteristics diagram.
