Overview
The AD9222ABCPZ-40 is an octal, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed for low cost, low power, small size, and ease of use, making it ideal for applications where space and power efficiency are critical. The AD9222 operates at conversion rates of up to 40 MSPS and is optimized for outstanding dynamic performance and low power consumption. It requires a single 1.8 V power supply and supports LVPECL-, CMOS-, and LVDS-compatible sample rate clocks. The ADC features an on-chip sample-and-hold circuit and does not require external reference or driver components for many applications.
