The AD9269 is a monolithic, dual-channel, 1.8 V supply, 16-bit, 20/40/65/80 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 AD9269 incorporates an optional integrated dc correction and quadrature error correction block (QEC) that corrects for dc offset, gain, and phase mismatch between the two channels. This functional block can be very beneficial to complex signal processing applications such as direct conversion receivers.

The ADC also 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 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 digital output data is presented in offset binary, gray code, or twos complement format. A data output clock (DCO) is pro-vided for each ADC channel to ensure proper latch timing with receiving logic. Both 1.8 V and 3.3 V CMOS levels are supported, and output data can be multiplexed onto a single output bus.

The AD9269 is available in a 64-lead RoHS-compliant LFCSP and is specified over the industrial temperature range (−40°C to +85°C).

Product Detail

This page contains evaluation board documentation and ordering information for evaluating the AD9269.

The AD9269-80EBZ is an evaluation board for the AD9269, dual 16-bit ADC. This reference design provides all of the support circuitry to operate devices in their various modes and configurations. It is designed to interface directly with the HSC-ADC-EVALCZ data capture card, allowing users to download captured data for analysis. The Visual Analog software package, which is used to interface with the device's hardware, allows users to download captured data for analysis with a user-friendly graphical interface. The SPI controller software package is also compatible with this hardware and allows the user to access the SPI programmable features of the AD9269.

The AD9269 data sheet provides additional information related to device configuration and performance and should be consulted when using these tools. All documents and Visual Analog and SPI Controller are available at the High Speed ADC Evaluation Boards page. For additional information or questions, please email highspeed.converters@analog.com.
