AD9484BCPZ-500

Analog To Digital Converters (ADC) Overview

The AD9484BCPZ-500 is an 8-bit, monolithic sampling analog-to-digital converter (ADC) optimized for high performance and low power. It operates at a maximum conversion rate of 500 MSPS with a full power analog bandwidth of 1 GHz. The device requires a single 1.8 V supply for both analog and digital sections. Key electrical parameters include a Signal-to-Noise Ratio (SNR) of 47 dBFS at 500 MSPS, an Effective Number of Bits (ENOB) of 7.5 bits, and a Spurious-Free Dynamic Range (SFDR) of 79 dBc at input frequencies up to 250 MHz. Differential Nonlinearity (DNL) and Integral Nonlinearity (INL) are typically ±0.1 LSB. Power dissipation in Single Data Rate (SDR) mode is 670 mW.
