GENERAL INFORMATION

DGND

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.

ADDRESS BUS

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.

ADDRESS

DECODER

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).

STROBE

SRI

LOAD

SRO

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.

LOAD

SRO

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

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-
