ADC12EU050CIPLQ/NOPB

Analog To Digital Converters (ADC) Overview

The ADC12EU050 is an octal, 12-bit continuous-time sigma-delta analog-to-digital converter (ADC) originally developed by National Semiconductor. It operates at sampling rates up to 50 MSPS with a total power consumption of 350 mW, equating to approximately 44 mW per channel. The device integrates a low-pass filter providing an alias-free signal bandwidth of 25 MHz and features resistive-input impedances that eliminate the need for external sample-and-hold amplifiers. It includes built-in PLL and VCO circuits for flexible clocking.
