The AD5066 is a fully accurate 16-bit unbuffered VOUT DAC with a 2.7 V to 5.5 V operating voltage range. It features an SPI interface and is suitable for applications such as industrial process control, data acquisition systems, and portable battery-powered instruments. The product offers low power consumption, fast settling time, individual reference pins for each channel, and per channel power-down functions.
The AD5066 DAC provides four independent 16‑bit voltage outputs in a 16‑lead TSSOP package. It operates from a single 2.7 V to 5.5 V supply and offers features such as individual reference pins, three power‑down modes, low‑glitch power‑up, and a high‑speed serial interface compatible with SPI, QSPI, Microwire, and DSP standards.
Typical applications include process control, data‑acquisition systems, portable battery‑powered instruments, and programmable voltage or current sources. The device includes hardware LDAC, programmable CLR, and supports both unipolar and bipolar output configurations.
