TP5531/TP5532/TP5534 1.8V,42μA,RRIO, Zero Drift Op-amps

　　The 3PEAK TP5531/2/4 low-power chopper stabilized operational amplifiers provide input offset voltage correction for very low offset and offset drift over time and temperature.The devices operate with a single supply voltage as low as 1.8V,while drawing 42μA per amplifier of quiescent current with a gain bandwidth product of 350kHz.They are unity gain stable,have no 1/f noise,have good Power Supply Rejection Ratio(PSRR)and Common Mode Rejection Ratio(CMRR),and feature railto-rail input and output swing.The devices were designed using an advanced CMOS process.The TP5531(single version)is available in SC70-5,SOT23-5 and SO-8 packages.The TP5532(dual version)is offered in MSOP-8 and SO-8 package.The TP5534(quad version)is available in TSSOP-14 and SOIC-14 package.All versions are specified for operation from-40°C to 125°C.
