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 / 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).
*Applications Active filters
Audio amplifiers VCOs Other electronic circuits
*Featuresoutput short-circuit protection circuit. 1) Built-in
2) Internal phase correction. 3) No latch-up.
4) Wide range of common-mode modes and differential voltage. 5) High gain and low noise.

*Operation notes circuits (1) Handling unused
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).
