Features and Benefits
- Improved Resistance to ESD
- Minimizes Address-Decoding in Multiple DAC Systems—Three-Wire Interface for Any Number of DACs:
One Data Line
One CLK Line
One Load Line
- Fast, Flexible, Microprocessor Interfacing in Serially Controlled systems
- Buffered Digital Output Pin for Daisy-Chaining Multiple DACs
- -40°C to +85°C for the Extended Industrial Temperature Range
The DAC8143 is a 12-bit serial-input, daisy-chain digital-to-analog converter. It was designed for multiple serial DAC systems where serial daisy-chaining one DAC after another is greatly simplified. The daisy chain feature saves address-decoding lines enabling simpler logic interfacing in multiple package DAC designs.
The DAV8143 is ideal for data acquisition and process control systems offering the user a wide flexibility in output voltage ranges through choices of external references and output I-to-V converter op amps.
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 updating 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 components. Fast interface timing reduces timing design considerations while minimizing microprocessor wait states.
The DAC8143 is available in plastic packages that are compatible with autoinsertion equipment.
Plastic packaged devices come in the extended industrial temperature range of –40°C to +85°C.

Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
