Operational Amplifiers

Low Noise Operational Amplifiers

BA4580Rxxx BA4584FV BA4584Rxx

General Description

BA4580Rxxx, BA4584FV, BA4584Rxx integrates two or

four independent high voltage gain Op-Amps on a

single chip. Especially, this series are suitable for any

audio applications due to low noise and low distortion

characteristics and are usable for other many

applications by wide operating supply voltage range.
