7.3.2 Low Input Offset Voltage

The OPAx325 are manufactured using TI's e-trim technology. Each amplifier is trimmed in production, thereby minimizing errors associated with input offset voltage. The e-trim technology is a TI proprietary method of trimming internal device parameters during either wafer probing or final testing. This process allows the OPAx325 to have an excellent offset specification of 150 µV (maximum). Figure 42 shows the offset voltage distribution for the OPAx325.
