DAC0854 Quad 8-Bit Voltage-Output  
Serial D/A Converter with Readback  
General Description  
Features  
Y
a
Single 5V supply operation  
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.  
Y
MICROWIRE serial interface allows easy interface to  
many popular microcontrollers including the COPSTM  
and HPCTM families of microcontrollers  
Data readback capability  
Y
Y
Output data can be formatted to read back MSB or  
LSB first  
Y
Versatile logic allows selective or global update of the  
DACs  
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.

Key Specifications  
Y
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.
