AD9287 is an 8-bit 100MSPS serial LVDS 1.8V A/D converter from Analog Devices (Agilent), with excellent linearity and low power characteristics, mainly used in medical imaging and nondestructive ultrasound applications
The AD9287 combines four 8‑bit analog‑to‑digital converters in a compact 48‑lead LFCSP package. It operates from a single 1.8 V supply and provides serial LVDS output with optional reduced‑signal mode. Features include 133 mW per channel power consumption at 100 MSPS, 295 MHz analog bandwidth, and programmable digital test patterns.
Typical applications are medical imaging, portable ultrasound, quadrature radio receivers, optical networking, and test equipment. The datasheet provides detailed specifications, functional block diagrams, timing diagrams, and pin configuration for system designers.

The AD9287 operates from a single 1.8 V supply (AVDD = 1.8 V, DRVDD = 1.8 V).
Four ADC channels are integrated into one package.
The device can convert at up to 100 MSPS.
Each channel consumes about 133 mW at 100 MSPS.
