GENERAL DESCRIPTION
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 DAC latch select one of the segments in a 16-resistor string.
Both taps of the segment are buffered by
amplifiers and f...
