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).
•Features current capacity. 1) High output
2) High slew rate.
3) Low noise.
