Operational Amplifiers
Low Noise Operational Amplifiers
BA2107G BA2115xxx
General Description
The BA2107/BA2115 are single and dual operational
amplifier with high gain and high slew rate(4v/µs).
The BA2107/BA2115 have good performance of input
referred noise voltage(7 nV/ Hz ) and total harmonic
distortion(0.008%). These are suitable for Audio
applications.
