AD9683BCPZRL7-250

Analog To Digital Converters (ADC) Overview

The AD9683BCPZRL7-250 is a 14-bit analog-to-digital converter (ADC) from Analog Devices Inc., designed for high-speed data acquisition in communications and test applications. It supports sampling rates up to 250 MSPS with an internal JESD204B serial interface capable of lane rates up to 5 Gbps. The device operates on a single 1.8 V supply, consuming 434 mW at maximum speed. Key electrical parameters include a signal-to-noise ratio (SNR) of 70.6 dBFS at 185 MHz input frequency and a spurious-free dynamic range (SFDR) of 88 dBc under the same conditions. It features a multistage differential pipelined architecture with integrated error correction logic.
