Dual high slew rate, low noise
operational amplifier
BA15532 / BA15532F / BA15532N
The BA15532, BA15532F, and BA15532N are low-noise dual operational amplifiers designed especially for applications involving high-grade audio equipment. Since they feature low noise, a wide band width, and high power output,
these products can also be used in measuring instruments and control circuits. The following packages are available
: 8-pin DIP (BA15532), 8-pin SOP (BA15532F), and 8-pin SIP (BA15532N).
•1)Features
High output current capacity.
3) Low noise.
2) High slew rate.

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).
