Overview
The AD9204BCPZRL7-65, produced by Analog Devices Inc., is a high-performance, monolithic, dual-channel analog-to-digital converter (ADC). It operates from a single 1.8 V analog power supply and features a separate digital output driver supply that can accommodate 1.8 V to 3.3 V logic families. This 10-bit ADC supports sampling rates of up to 65 MSPS and is designed for low power consumption, ease of use, and high accuracy.
The AD9204 uses a multistage differential pipeline architecture with output error correction logic to ensure 10-bit accuracy and guarantee no missing codes over the full operating temperature range. It is packaged in a 64-lead RoHS compliant LFCSP, making it pin compatible with other ADCs from Analog Devices, such as the AD9268, AD9251, and AD9231, facilitating easy migration between different converter types.
