44-Lead MQFP Package The AD7841 contains eight 14-bit DACs on one monolithic
chip. It has output voltages with a full-scale range of ± 10 V
from reference voltages of ± 5 V.
The AD7841 accepts 14-bit parallel loaded data from the external bus into one of the input registers under the control of the
WR, CS, and DAC channel address pins, A0–A2.
The DAC outputs are updated on reception of new data into
the DAC registers. All the outputs may be updated simultaneously by taking the LDAC input low. APPLICATIONS
Automatic Test Equipment
Process Control
General Purpose Instrumentation Each DAC output is buffered with a gain-of-two amplifier into
which an external DAC offset voltage can be inserted via the
DUTGNDx pins. …
