The AD9266 is a monolithic, single-channel 1.8 V supply, 16-bit, 20 MSPS/40 MSPS/65 MSPS/80 MSPS analog-to-digital converter (ADC). It features a high performance sample-and-hold circuit and on-chip voltage reference.
The product uses multistage differential pipeline architecture with output error correction logic to provide 16-bit accuracy at 80 MSPS data rates and to guarantee no missing codes over the full operating temperature range.
The ADC contains several features designed to maximize flexibility and minimize system cost, such as programmable clock and data alignment and programmable digital test pattern generation. The available digital test patterns include built-in deterministic and pseudorandom patterns, along with custom user-defined test patterns entered via the serial port interface (SPI).
A differential clock input with a selectable internal 1-to-8 divide ratio controls all internal conversion cycles. An optional duty cycle stabilizer (DCS) compensates for wide variations in the clock duty cycle while maintaining excellent overall ADC performance.
The interleaved digital output data is presented in offset binary, gray code, or twos complement format. A DCO is provided to ensure proper latch timing with receiving logic. Both 1.8 V and 3.3 V CMOS levels are supported.
The AD9266 is available in a 32-lead RoHS-compliant LFCSP and is specified over the industrial temperature range (−40°C to +85°C).
- The AD9266 operates from a single 1.8 V analog power supply and features a separate digital output driver supply to accommodate 1.8 V to 3.3 V logic families.
- The sample-and-hold circuit maintains excellent performance for input frequencies up to 200 MHz and is designed for low cost, low power, and ease of use.
- A standard serial port interface supports various product features and functions, such as data output formatting, internal clock divider, power-down, DCO and data output (D15_D14 to D1_D0) timing and offset adjustments, and voltage reference modes.
- The AD9266 is packaged in a 32-lead RoHS-compliant LFCSP that is pin compatible with the AD9609 10-bit ADC, the AD9629 12-bit ADC, and the AD9649 14-bit ADC, enabling a simple migration path between 10-bit and 16-bit converters sampling from 20 MSPS to 80 MSPS.

Tools & Simulations
Virtual Eval - BETA
Virtual Eval is a web application to assist designers in product evaluation of ADCs, DACs, and other ADI products. Using detailed models on Analog’s servers, Virtual Eval simulates crucial part performance characteristics within seconds. Configure operating conditions such as input tones and external jitter, as well as device features like gain or digital down-conversion. Performance characteristics include noise, distortion, and resolution, FFTs, timing diagrams, response plots, and more.
For designers who are selecting or evaluating high speed ADCs, VisualAnalog™ is a software package that combines a powerful set of simulation and data analysis tools with a user-friendly graphical interface.
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
