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
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.

•Operation notes
(1) Unused circuit connections
If there are any circuits which are not being used, we
recommend making connections as shown in Figure 9,
with the non-inverted input pin connected to the poten-
tial within the in-phase input voltage range (VICM).
