ROHM BA4560N

Standard ICs
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).

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
(VICM).
