The DAC7612 is a dual, 12-bit digital-to-analog converter (DAC) with guaranteed 12-bit monotonicity performance over the industrial temperature range. It requires a single +5V supply and contains an input shift register, latch, 2.435V reference, a dual DAC, and high speed rail-to-rail output amplifiers. For a full- scale step, each output will settle to 1 LSB within 7µs while only consuming 3.7mW. The synchronous serial interface is compatible with a wide variety of DSPs and microcontrollers. Clock (CLK), Serial Data In (SDI), Chip Select (CS) and Load DACs (LOADDACS) comprise the serial interface. The DAC7612 is available in an 8-lead SOIC package and is fully specified over the industrial temperature range of –40°C to +85°C.
The DAC7612 is a dual, 12‑bit digital‑to‑analog converter offered by Texas Instruments (originally Burr‑Brown). It operates from a single +5 V supply and provides rail‑to‑rail output amplifiers with low power consumption (3.7 mW). The device features a 3‑wire serial interface compatible with a wide range of DSPs and microcontrollers.
The datasheet includes full specifications, pin configuration, absolute maximum ratings, timing diagrams, typical performance curves, and package information. It also contains legal notices and ordering details for the SOIC‑8 package versions DAC7612U and DAC7612UB.
