The AD9231 is a monolithic, dual-channel, 1.8 V supply, 12-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 12-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 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 provided 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 AD9231 is available in a 64-lead RoHS compliant LFCSP and is specified over the industrial temperature range (−40°C to +85°C).
PRODUCT HIGHLIGHTS
- The AD9231 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 patented 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/DATA timing and offset adjustments, and voltage reference modes.
- The AD9231 is packaged in a 64-lead RoHS compliant LFCSP that is pin compatible with the AD9268 16-bit ADC, the AD9258 14-bit ADC, the AD9251 14-bit ADC, and the AD9204 10-bit ADC, enabling a simple migration path between 10-bit and 16-bit converters sampling from 20 MSPS to 125 MSPS.

Product Detail
This page contains evaluation board documentation and ordering information for evaluating the AD9231.
The AD9231-80EBZ is an evaluation board for the AD9231, dual 12-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 AD9231.
The AD9231 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.
