The AD7846 is a 16-bit DAC constructed with the Analog Devices,
Inc., LC2MOS process. It has VREF+ and VREF− reference inputs
and an on-chip output amplifier. These can be configured to
give a unipolar output range (0 V to +5 V, 0 V to +10 V) or
bipolar output ranges (±5 V, ±10 V).
The DAC uses a segmented architecture. The four MSBs in the …
