Low Noise Operational Amplifiers
BA4558xxx, BA4558Rxxx
●General Description
Normal BA4558 and high-reliability BA4558R integrate two 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 are usable for other many applications by wide operating supply voltage range.BA4558R is high-reliability products with extended operating temperature range and high ESD tolerance.
●Features
High voltage gain, low noise, low distortion Wide operating supply voltage Internal ESD protection Wide operating temperature Range
