The OPAx206 are the industry's first e-trim operational amplifiers built on a bipolar process. The input offset voltage of an amplifier is determined by the inherent mismatch between the input transistors. The offset can be minimized using laser-trimming performed during the manufacturing process while the device is still in the bare silicon form. However, when the silicon is packaged, the packaging process introduces additional offset due to mechanic stresses. TI's new trimming processes are used to trim the offset after the packaging process is complete to minimize both inherent and package-induced offsets. After trimming, communication is disabled to make sure the amplifier operates properly in the final system.
A comparison between production offset values for a the industry popular, laser-trimmed OPA2277 amplifier and the OPAx206 proprietary trim can be seen in Figure 7-3 and Figure 7-4.
The OPAx206 also features exceptional input offset voltage drift over temperature. Figure 7-5 shows the final performance of the offset drift.
