The DAC081C081 is an 8-bit, single channel, voltage-output digital-to-analog converter (DAC) that operates from a +2.7V to 5.5V supply. It has a fast settling time and wide dynamic output range, making it suitable for low-power applications. The DAC081C085 is an alternative to the DAC081C081 with more address options and an external reference voltage feature.
The DAC081C081 and DAC081C085 are 8‑bit, single‑channel voltage‑output digital‑to‑analog converters that operate from a +2.7 V to 5.5 V supply. They feature a rail‑to‑rail output swing, 4.5 µs settling time, and ultra‑low power consumption (down to sub‑pW in power‑down mode). The DAC081C081 uses the supply voltage as its reference, while the DAC081C085 uses an external reference and offers nine I²C address options.
Both devices support a 2‑wire I²C‑compatible serial interface with three speed modes (standard 100 kHz, fast 400 kHz, high‑speed 3.4 MHz) and are available in compact TSOT‑6, LLP‑6, and MSOP‑8 packages. They operate over an industrial temperature range of –40 °C to +125 °C and are suitable for portable instruments, industrial process control, and test equipment.
