AD9253 is a Quad, 14-Bit, 80 MSPS/105 MSPS/125 MSPS Serial LVDS 1.8 V Analog-to-Digital Converter. It features 1.8 V supply operation, low power consumption, high signal-to-noise ratio, low non-linearity, etc. It is suitable for applications such as medical ultrasound, high-speed imaging, quadrature radio receivers, etc.
The AD9253 is a quad, 14‑bit analog‑to‑digital converter that operates from a single 1.8 V supply and supports conversion rates up to 125 MSPS. It provides LVDS, CMOS and LVPECL serial outputs, programmable test patterns, and flexible power‑down modes, all in a compact 48‑lead LFCSP package.
Designed for medical ultrasound, high‑speed imaging, quadrature radio receivers and test equipment, the device includes detailed design guidelines for power distribution, grounding, PCB layout, and SPI interfacing to ensure optimal performance across its –40 °C to +85 °C temperature range.
