8.1 Application Information

The OPAx325 series features e-trim, a proprietary technique in which the offset voltage is adjusted during the final steps of manufacturing. As a result, the OPAx325 deliver excellent offset voltage (40 μV, typical). Additionally, the amplifier boasts a fast slew rate, low drift, low noise, and excellent PSRR and A_OL. The OPAx325 also feature a linear input stage with zero-crossover distortion, resulting in excellent CMRR over the entire input range, which extends from 100 mV below the negative rail to 100 mV above the positive rail.
