AD9023BQ

Overview

The AD9023BQ is a high-performance, dual-channel analog-to-digital converter (ADC) from Analog Devices. It features a sampling rate of up to 125 MSPS with an input bandwidth of 60 MHz. The device integrates a 14-bit resolution and supports multiple power-down modes for energy efficiency. It operates on a single 3.3 V supply and includes internal reference and clock drivers. The ADC utilizes a differential input architecture to enhance dynamic performance metrics such as SNR and SFDR. It is housed in a compact 48-lead LFCSP package suitable for space-constrained designs.
