AD5532HS is a 32-channel 14-bit DAC with a high-speed serial interface.
The AD5532HS integrates 32 DAC channels in a 74‑ball LFBGA package, providing 14‑bit resolution and guaranteed monotonicity. It operates from a 5 V analog supply and a 2.7‑5.25 V digital supply, with selectable output ranges of 0 V‑5 V or –2.5 V‑+2.5 V.
The device features a 3‑wire serial interface compatible with DSP and microcontroller standards, supporting clock rates up to 30 MHz and a channel update rate of 1.1 MHz. It includes built‑in ESD protection, a reset function, and extensive specifications for power, timing, and performance. This manual is written in Chinese.
