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 data rates and guarantees...
The AD9280 is a monolithic, single‑supply, 8‑bit, 32 MSPS analog‑to‑digital converter featuring an on‑chip sample‑and‑hold amplifier, programmable reference, and out‑of‑range indicator. It operates from +2.7 V to +5.5 V and consumes only 95 mW at a 3 V supply, making it suitable for low‑power, high‑speed imaging and communications applications.
The document provides detailed specifications, pin configuration, functional block diagram, grounding and layout recommendations, and mechanical dimensions for the 28‑lead SSOP package. It also defines key performance metrics such as DNL, INL, SNR, THD, and power‑down mode behavior.
