零偏移放大器：AD8230概览Zero-Drift Amplifiers: A Look at the AD8230 Some applications require extreme precision over temperature and AD8230 OUTPUT VOLTAGE vs. MAXIMUM COMMON-MODE VOLTAGE time. In many instances, an instrument can only be calibrated dur- ing manufacture; designers must ensure that the system does not 6 drift out of specification afterwards. Such applications call for “zero- drift” instrumentation amplifiers such as the AD8230. It uses an 4 offset correction scheme, referred to as auto-zeroing, to reduce its ……
