Overview
The AD9266BCPZ-65, produced by Analog Devices Inc., is a high-performance, single-channel 16-bit analog-to-digital converter (ADC). This monolithic device 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. The AD9266 uses a multistage differential pipeline architecture with output error correction logic, ensuring 16-bit accuracy at sampling rates up to 80 MSPS and guaranteeing no missing codes over the full operating temperature range.
The device is packaged in a 32-lead RoHS-compliant LFCSP, which is pin compatible with other ADCs from Analog Devices, such as the AD9609, AD9629, and AD9649, facilitating easy migration between different converter resolutions and sampling rates.
