The AD9280 is a monolithic, single supply, 8-bit, 32 MSPS analog-to-digital converter with an on-chip sample-and-hold amplifier and voltage reference. The AD9280 uses a multistage differential pipeline architecture at 32 MSPS to achieve high linearity and low power consumption.
The AD9280 is a monolithic, single‑supply, 8‑bit, 32 MSPS analog‑to‑digital converter designed for imaging and communications systems. It offers selectable input ranges, differential or single‑ended operation, an on‑chip sample‑and‑hold, and a programmable voltage reference.
The datasheet provides detailed specifications, pin configuration, electrical characteristics, operational modes, grounding and layout recommendations, as well as package dimensions for the 28‑lead SSOP (RS‑28) device.
