GENERAL DESCRIPTION
●The AD9248 is a dual, 3 V, 14- bit, 20/40/65 MSPS analog - to digital converter. It features dual high performance sample- and hold amplifiers and an integrated vol tage reference. The AD9248 uses a multistage differential pipelined architecture with output error correction logic to provide 14- bit accuracy
●and guarantee no missing codes over the full operating temperature range at up to 65 MSPS data rates. The wide bandwidth, differential SHA allows for a variety of user selectable input ranges and offsets including single - ended applications. It is suitable for various applications including multiplexed systems that switch full- scale voltage levels in successive chann els and for sampling inputs at frequencies well
●beyond the Nyquist rate.
