产品概述 返回TOP
The CXAO42143A/B are rail-to-rail input and output precision operational amplifiers which have low input offset voltage, and bias current. They are guaranteed to operate from 2.5V to 5.5V single supply.
The rail-to-rail input and output swings provided by the CXAO42143A/B make both high-side and low-side sensing easy. The combination of characteristics makes the CXAO42143A/B good choices for temperature, position and pressure sensors, medical equipment and strain gauge amplifiers, or any other 2.5V to 5.5V application requiring precision and long term stability.
The single CXAO42143A is available in the Green SOT-23-5, SOIC-8 and MSOP-8 packages. The dual CXAO42143B is available in the Green SOIC-8 and MSOP-8 packages. They are specified for the extended industrial/automotive (-40℃ to +125℃) temperature range.
