Overview
The AD9284BCPZRL7-250, produced by Analog Devices Inc., is a dual 8-bit, monolithic sampling analog-to-digital converter (ADC) designed for high-speed applications. It operates at up to 250 million samples per second (MSPS) and is optimized for low cost, low power consumption, and ease of use. The ADC supports simultaneous operation of its two channels and features a single 1.8 V supply operation with LVDS (Low Voltage Differential Signaling) compatible outputs. This component is particularly useful in various high-speed data acquisition and signal processing applications.
