Operational Amplifiers

BA3404xxx

●General Description

BA3404 is a dual operational amplifier with input and

output ground sense. Especially, BA3404 have wide

operating voltage range +4V to +36V (single supply).

BA3404 have a good performance of slew rate and

cross over distortion compare with BA2904.
