The DAC128S085 is a 12-bit micro power octal digital-to-analog converter with rail-to-rail outputs, which can operate from a single +2.7V to +5.5V supply and consumes only 1.95 mW of power.
The DAC128S085 is a full‑feature, 12‑bit octal DAC that operates from a single +2.7 V to +5.5 V supply and consumes as little as 1.95 mW at 3 V. It is offered in 16‑lead LLP and TSSOP packages, providing the smallest octal DAC in its class. The device includes rail‑to‑rail output amplifiers, a three‑wire serial interface compatible with SPI, QSPI, Microwire and DSP, and supports daisy‑chain operation for unlimited devices.
Key features include guaranteed monotonicity, low power operation, dual reference voltages (0.5 V to VREF), and a wide operating temperature range of –40 °C to +125 °C. The datasheet provides detailed electrical characteristics, pin configurations, timing diagrams, and ordering information for designers.
