Operational Amplifier
Low Noise Operational Amplifier
BA15532F
General Description
BA15532F is a low noise operational amplifier of high
voltage gain. It excels especially in input referred noise
voltage (0.7μVrms), total harmonic distortion ratio
(0.0015%) and operating voltage range (±3.0V to
±20.0V) and it is the most suitable operational amplifier
for audio equipments.
