OPAx328 Operational Amplifiers

Texas Instruments OPAx328 Operational Amplifiers are single-channel and dual-channel precision, low-voltage CMOS operational amplifiers optimized for low noise and wide bandwidth. The OPAx328 features a linear input stage with zero crossover distortion that allows an excellent common mode rejection ratio (CMRR) of 120dB (typical) over the full input range. The device's input common-mode voltage range extends 100mV beyond the negative and positive supply rails.
