DAC0854 Quad 8-Bit Voltage-Output
Serial D A Converter with Readback
General Description
The DAC0854 is a complete quad 8-bit voltage-output digi-
tal-to-analog converter that can operate on a single 5V sup-
ply It includes on-chip output amplifiers internal voltage ref-
erence and a serial microprocessor interface By combining
in one package the reference amplifiers and conversion
circuitry for four D A converters the DAC0854 minimizes
wiring and parts count and is hence ideally suited for appli-
cations where cost and board space are of prime concern
The DAC0854 also has a data readback function which can
be used by the microprocessor to verify that the desired
input word has been properly latched into the DAC0854’s
data registers The data readback function simplifies the de-
sign and reduces the cost of systems which need to verify
data integrity
The logic comprises a MICROWIRETM-compatible serial in-
terface and control circuitry The interface allows the user to
write to any one of the input registers or to all four at once
The latching registers are double-buffered consisting of 4
separate input registers and 4 DAC registers Double buffer-
ing allows all 4 DAC outputs to be updated simultaneously
The four reference inputs allow the user to configure the
system to have a separate output voltage range for each
DAC The output voltage of each DAC can range between
0 3V and 2 8V and is a function of VBIAS VREF and the
input word
