This document describes the features and characteristics of a Quad, 14-bit, 50 MSPS Serial LVDS 1.8 V ADC product, including power consumption per channel, signal-to-noise ratio, effective number of bits, linearity, etc.
The AD9259 ADC integrates four 14‑bit converters in a compact 48‑lead LFCSP package, delivering up to 50 MSPS conversion rate with 98 mW per channel power consumption. It operates from a single 1.8 V supply and provides LVDS, LVPECL, or CMOS‑compatible serial data interfaces, eliminating the need for external reference circuitry.
The device offers programmable clock and data alignment, built‑in digital test pattern generation, and individual‑channel power‑down. Detailed specifications include 315 MHz analog bandwidth, 73 dB SNR, 12‑bit ENOB, and a wide operating temperature range of –40 °C to +85 °C.
