3PEAK TP5532-SR

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 34μA 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 rail-to-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.
