Overview
The AD9233BCPZRL7-105 is a high-performance, monolithic 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device operates from a single 1.8 V power supply and features a separate digital output driver supply that can accommodate 1.8 V to 3.3 V logic families. It is designed for high-speed data acquisition systems and utilizes a multistage differential pipeline architecture with output error correction logic to ensure 12-bit accuracy at sampling rates of up to 125 MSPS. The AD9233 also includes a high-performance sample-and-hold amplifier (SHA) and an on-chip voltage reference, making it suitable for various demanding applications.
