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 /

µ

s, 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

).
