Dual high slew rate operational
amplifier
BA4560 / BA4560F / BA4560N
The BA4560, BA4560F, and BA4560N are dual operational amplifiers which achieve approximately twice the high
output current of the BA4558, as well as featuring a higher slew rate of 4V / µs, a gain band width of 10MHz, and an
improved frequency characteristic. The following packages are available: 8-pin DIP (BA4560), 8-pin SOP (BA4560F),
and 8-pin SIP (BA4560N).

Operation notes
(1) Handling unused circuits
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
potential within the in-phase input voltage range
(V
ICM).
