The 3PEAK TP5531/2/4 low-power chopper stabilizedoperational amplifiers provide input offset voltagecorrection for very low offset and offset drift over time andtemperature. The devices operate with a single supplyvoltage as low as 1.8V, while drawing 42μA per amplifierof quiescent current with a gain bandwidth product of350kHz. They are unity gain stable, have no 1/f noise,have good Power Supply Rejection Ratio (PSRR) andCommon Mode Rejection Ratio (CMRR), and feature railto-rail input and output swing.The devices were designed using an advanced CMOSprocess. The TP5531 (single version) is available inSC70-5, 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 andSOIC-14 package. All versions are specified for operationfrom -40°C to 125°C.
