PRODUCTION DATA.
Most applications require no external offset adjustment; however, if necessary, adjustments can be made by applying a voltage to the REF pin. Figure 56 shows an optional circuit for trimming the output offset voltage. The voltage applied to the REF pin is summed at the output. The op amp buffer provides low impedance at the REF pin to preserve good common-mode rejection.
