The AD5532 is a 32-channel, 14-bit voltage-output DAC with an additional infinite sample-and-hold mode. The selected DAC register is written to via the 3-wire serial interface; VOUT for this DAC is then updated.
The AD5532 is a 32‑channel, 14‑bit voltage‑output digital‑to‑analog converter offered in a 74‑lead CSPBGA package. It provides guaranteed monotonic operation, selectable output voltage ranges, and both 3‑wire serial and parallel interfaces for microcontroller integration. The device includes an infinite sample‑and‑hold mode and read‑back capability, making it suitable for test equipment, optical networks, and data‑acquisition systems.
The datasheet details electrical specifications such as 14‑bit resolution, ±0.39 % INL, 1 LSB DNL, and typical output impedances ranging from 0.5 Ω to 1 kΩ. Supply requirements include AVcc 4.75‑5.25 V and DVcc 2.7‑5.25 V, with an industrial temperature range of –40 °C to +85 °C. Pin configurations, timing diagrams, absolute maximum ratings, and application circuits are also provided.
