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).

BA15218 Features
1) 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 = 1.0mVrms typ. : RIAA) 3) High slew rate. (SR = 3V / ms, 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.
