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 single-channel and multichannel data acquisition systems with high performance and low cost requirements.
The DAC8143 provides a 12‑bit resolution D/A conversion with a three‑wire interface (data, clock, load) that allows unlimited daisy‑chaining of devices. It features buffered digital output pins, minimized address decoding, and extended industrial temperature operation from –40 °C to +85 °C.
The device is supplied in 16‑lead plastic DIP and SOIC packages, supports a supply voltage of 4.75 V to 5.25 V, and includes ESD protection on its digital inputs. Detailed electrical characteristics, timing specifications, and application notes are provided for use in data‑acquisition, process control, and test equipment.
