GENERAL INFORMATION
The DAC8143 is a 12-bit serial-input daisy-chain CMOS D/A
converter that features serial data input and buffered serial data
output. It was designed for multiple serial DAC systems, where
serially daisy-chaining one DAC after another is greatly simplified.
The DAC8143 also minimizes address decoding lines enabling
simpler logic interfacing. It allows three-wire interface for any
number of DACs: one data line, one CLK line and one load line.
Serial data in the input register (MSB first) is sequentially
clocked out to the SRO pin as the new data word (MSB first) is
simultaneously clocked in from the SRI pin. The strobe inputs
are used to clock in/out data on the rising or falling (user
selected) strobe edges (STB1, STB2, STB3, STB4).
When the shift register’s data has been updated, the new data
word is transferred to the DAC register with use of
LD1 and
LD2 inputs.
Separate LOAD control inputs allow simultaneous output up-
dating of multiple DACs. An asynchronous CLEAR input
resets the DAC register without altering data in the input
register.
Improved linearity and gain error performance permits reduced
circuit parts count through the elimination of trimming compo-
nents. Fast interface timing reduces timing design considerations
while minimizing microprocessor wait states.
The DAC8143 is available in plastic packages that are compat-
ible with autoinsertion equipment.
Plastic packaged devices come in the extended industrial tem-
perature range of –40
°C to +85°C.
