Overview
The AD9218BSTZ-105 is a dual 10-bit monolithic sampling analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed for high-performance applications, offering low power consumption, small size, and ease of use. It operates at conversion rates of 40, 65, 80, and 105 MSPS, with each channel capable of independent operation. The ADC requires a single 3.0 V power supply (operating range of 2.7 V to 3.6 V) and a clock for full operation, eliminating the need for external reference or driver components in many applications.
