OPA2325
Overview
The OPA325, OPA2325, and OPA4325 (OPAx325) are precision, low-voltage complementary metal-oxide semiconductor (CMOS) operational amplifiers optimized for very low noise and wide bandwidth, while operating on a low quiescent current of only 650 μA. The OPAx325 feature a linear input stage with zerocrossover distortion that delivers excellent commonmode rejection ratio (CMRR) of typically 114 dB over the entire input range.
