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).
