AD9259 Rev.B is a 14-bit 50MSPS serial LVDS 1.8V converter, providing 4 ADCs, low power consumption, good linearity, support for serial port control, power-down mode and other features.
The AD9259 is a quad, 14‑bit analog‑to‑digital converter capable of up to 50 MSPS conversion rate. It operates from a single 1.8 V supply and provides LVDS, LVPECL, or CMOS‑compatible outputs, with built‑in digital test pattern generation and programmable clock/data alignment.
Designed for compact, low‑power applications, the device is offered in a RoHS‑compliant 48‑lead LFCSP and is specified over an industrial temperature range (‑40 °C to +85 °C). Typical applications include medical imaging, portable ultrasound, quadrature radio receivers, optical networking, and test equipment.
