The AD5441 is a high accuracy 12-bit multiplying digital-to-analog converter (DAC) in space-saving 8-lead packages. Featuring serial input, double buffering, and excellent analog performance, the AD5441 is ideal for applications where PC board space is at a premium.
The AD5441 is a high‑accuracy 12‑bit multiplying digital‑to‑analog converter featuring a 2.5 V to 5.5 V supply range, true 12‑bit resolution, and fast 3‑wire serial input. It is suited for PLCs, programmable amplifiers, digitally controlled calibration, and motion‑control systems. The device integrates a shift register, DAC register, CMOS DAC, and control logic, consuming only about 1 µA from a single 5 V supply.
The datasheet provides detailed electrical and timing characteristics, absolute maximum ratings, thermal resistance data, pin configurations for both 8‑lead LFCSP and MSOP packages, and typical performance graphs. Specifications such as resolution, supply current, operating temperature range, and multiplying bandwidth are listed for designers.
