Operational Amplifier series
Low Noise Operational Amplifiers
BA14741F, BA14741FJ
General Description
General-purpose BA14741 integrates four
independent Op-Amps on a single chip. Especially, this
series is suitable for any audio applications due to low
noise and low distortion characteristics and is usable
for other many applications by wide operating supply
voltage range.
