This is the datasheet of TI's DAC7568, DAC8168, DAC8568, which are low-power, eight-channel, 12/14/16-bit digital-to-analog converters (DACs), with 2.5V, 2ppm/°C internal reference, programmable attenuation, digital gain and offset adjustment, programmable voltage and current sources.
The DAC7568, DAC8168, and DAC8568 are low‑power, voltage‑output, eight‑channel digital‑to‑analog converters offering 12‑, 14‑, and 16‑bit resolution respectively. They include a 2.5 V, 2 ppm/°C internal reference (disabled by default), 20 mA sink/source capability, and operate over a wide supply range of +2.7 V to +5.5 V. Features such as ultra‑low glitch energy (0.1 nV‑s) and low‑power serial interfaces support high‑speed SPI/QSPI/Microwire communication up to 50 MHz.
The datasheet details electrical characteristics, pin‑out diagrams for TSSOP‑14 and TSSOP‑16 packages, timing diagrams, and mechanical dimensions. It also includes typical performance graphs for the internal reference, long‑term stability, and an important notice on warranty and safety‑critical usage.
