Overview
The AD9266BCPZRL7-20 is a high-performance, 16-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This monolithic, single-channel ADC operates from a single 1.8 V analog power supply and supports digital output driver supplies ranging from 1.8 V to 3.3 V. It features a multistage differential pipeline architecture with output error correction logic, ensuring 16-bit accuracy at data rates up to 80 MSPS and guaranteeing no missing codes over the full operating temperature range.The AD9266 includes a high-performance sample-and-hold circuit and an on-chip voltage reference, making it suitable for a variety of high-speed applications. The device is packaged in a 32-lead RoHS-compliant LFCSP, which is pin compatible with other ADCs from Analog Devices, facilitating easy design migration between different resolutions and sampling rates.
