Gain of Two Configuration (×2 Gain Mode)
Figure 54 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 × V
V
output span from a single-ended reference input, with V
0 V. For this mode of operation, the RBUF bit of the control
register must be cleared to Logic 0.
