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
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 = 1.0µVrms 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 characteris
   tics make these products compatible with the 4558
   and 4560 models.
