AD5532 Rev. D is a 32-channel, 14-bit voltage-output DAC. It features high integration, adjustable voltage output range, guaranteed monotonicity, and readback capability.
The AD5532 provides 32 independent 14‑bit DAC channels in a 12 mm × 12 mm CSPBGA package. It features guaranteed monotonic performance, droop‑less infinite sample‑and‑hold, and selectable output voltage ranges set by the OFFS_IN pin and output‑amp gain. Both 3‑wire serial and 5‑wire parallel interfaces are supported, with optional ISHA mode for simultaneous acquisition.
Typical applications include automatic test equipment, optical networking, instrumentation, and industrial control systems. The device operates from standard analog and digital supplies (VDD 8‑16.5 V, VSS –4.75‑‑16.5 V, AVCC 5 V, DVCC 2.7‑5.25 V) and offers a reference input of 3 V. Detailed timing diagrams, pin configurations, and microprocessor interfacing examples are provided.
