Overview
The AD9225ARSZRL is a monolithic, single-supply, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This component operates at a sampling rate of 25 million samples per second (MSPS) and is designed for high-speed, high-accuracy data conversion. The AD9225 uses a multi-stage differential pipelined architecture with output error correction logic to ensure 12-bit accuracy and guarantees no missing codes over the full operating temperature range. It is fabricated on a cost-effective CMOS process, combining high-speed precision analog circuits with high-density logic circuits.
