Gain of Two Configuration (×2 Gain Mode)

Figure 53 shows an output amplifier configured for a gain of

two. The gain is set by the internal matched 6.8 kΩ resistors,

which are exactly twice the DAC resistance, having the effect

of removing an offset from the input bias current of the external

amplifier. In this configuration, the output spans from 2 × VREFN −

VREFP to VREFP. This configuration is used to generate a bipolar

output span from a single-ended reference input, with VREFN =

0 V. For this mode of operation, the RBUF bit of the control

register must be cleared to Logic 0.
