AD9252ABCPZ-50

Analog To Digital Converters (ADC) Overview

The AD9252ABCPZ-50 is an octal, 14-bit analog-to-digital converter operating at a maximum sampling rate of 50 MSPS. It integrates eight independent ADC channels within a single 64-lead LFCSP package. The device utilizes a pipelined architecture with an on-chip sample-and-hold circuit and requires a single 1.8 V power supply for both analog and digital domains. It features serial LVDS outputs compliant with ANSI-644, providing data clock (DCO) and frame clock (FCO) signals. Key performance metrics include a signal-to-noise ratio of 73.2 dB at 2.4 MHz input frequency, a full-power analog bandwidth of 325 MHz, and a differential input voltage range of 2 V p-p. Total power dissipation is approximately 748 mW.
