3 Description
The single-channel OPA328 and dual-channel OPA2328 (OPAx328) are a new generation family of precision, low-voltage CMOS operational amplifiers optimized for very low noise and wide bandwidth.
The OPAx328 have a linear input stage with zerocrossover distortion that delivers excellent monmode rejection...
