BA15532 / BA15532F / BA15532N
The BA15532, BA15532F, and BA15532N are low-noise dual operational amplifiers designed especially for applica-
tions 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).
