AD9286 is an 8-bit, 500 MSPS, 1.8 V analog-to-digital converter (ADC) from Analog Devices. It features single 1.8 V supply operation, high signal-to-noise ratio (SNR), high dynamic range (SFDR), low power consumption, and is suitable for battery-powered instruments, handheld scope meters, and low-cost digital oscilloscopes.
The AD9286 is an 8‑bit, 500 MSPS analog‑to‑digital converter (ADC) optimized for low cost and low power. It operates from a single 1.8 V supply, provides LVDS‑compatible differential digital outputs, and includes on‑chip reference, clocking, and a pin‑programmable power‑down function.
The datasheet includes full specifications, pin configurations, timing diagrams, absolute maximum ratings, thermal data, and design guidelines for PCB layout and power distribution. It also provides a memory‑map register description and SPI interface details for configuring the device.
