零偏移放大器:AD8230概览Zero-Drift Amplifiers:A Look at the AD8230Some applications require extreme precision over temperature and AD8230OUTPUT VOLTAGE vs.MAXIMUM COMMON-MODE VOLTAGEtime.In many instances,an instrument can only be calibrated dur-ing manufacture;designers must ensure that the system does not6drift out of specification afterwards.Such applications call for“zero-drift”instrumentation amplifiers such as the AD8230.It uses an4offset correction scheme,referred to as auto-zeroing,to reduce its
