Zero-Drift, Single-Supply, Rail-to-Rail Input/ Output Operational Amplifiers CXOA42294

产品概述

返回TOP

The CXOA42293 , CXOA42294 and CXOA 42295 are single, dual and quad amplifiers featuring rail-to-rail input and output swings, which has ultralow offset, drift and bias current. All are guaranteed to operate from +1.8 V to +5 V single supply. With an offset voltage of only 80 µV and drift of 20 nV /° C , the CXOA 42294 is perfectly suited for applications where error sources cannot be tolerated . Temperature , position and pres -sure sensors , medical equipment and strain gage amplifiers benefit greatly from nearly zero drift over their operating temperature range. The rail-to-rail input and output swings provided by the CXOA42294 family make both high -side and low- side sensing easy. 
The CXOA42294 series is specified for the extended industrial /automotive (–40°C to +125 °C) temperature range. The CXOA42294 single is available in 5-lead SOT and 8-lead SOP/MSOP packages. The CXOA42295 dual amplifier is available in 8-lead SOP /MSOP packages. The CXOA42293 quad is available in narrow 14-lead SOP and 14-lead TSSOP packages.
