7.1.4 Offset Trimming

The INA141 is laser trimmed for low offset voltage and offset voltage drift. Most applications require no external offset adjustment. Figure 7-2 shows an optional circuit for trimming the output offset voltage. The voltage applied to Ref pin is summed with the output. The op-amp buffer provides low impedance at the Ref pin to preserve good common-mode rejection.
