Description
The XPTEK XPT2231/2/4 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.
