Overview
The AD9218BSTZ-RL65, produced by Analog Devices Inc., is a dual 10-bit monolithic sampling analog-to-digital converter (ADC) with on-chip track-and-hold circuits. This component is designed to be low cost, low power, and compact, making it easy to integrate into various systems. It operates at conversion rates of 40, 65, 80, and 105 MSPS, offering high dynamic performance across its full operating range. Each channel can be operated independently, and the ADC requires only a single 3.0 V power supply and a clock for full operation.
