●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.
