The AD9258 is a dual, 14-bit, 80 MSPS/105 MSPS/125 MSPS analog-to-digital converter (ADC). The AD9258 is designed to support communications applications where high performance, combined with low cost, small size, and versatility, is desired.
The dual ADC core features a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth differential sample-and-hold analog input amplifiers that support a variety of user-selectable input ranges. An integrated voltage reference eases design considerations. A duty cycle stabilizer is provided to compensate for variations in the ADC clock duty cycle, allowing the converters to maintain excellent performance.
The ADC output data can be routed directly to the two external 14-bit output ports. These outputs can be set to either 1.8 V CMOS or LVDS.
Flexible power-down options allow significant power savings, when desired.
Programming for setup and control is accomplished using a 3-wire SPI-compatible serial interface.
The AD9258 is available in a 64-lead LFCSP and is specified over the industrial temperature range of −40°C to +85°C.
PRODUCT HIGHLIGHTS
- On-chip dither option for improved SFDR performance with low power analog input.
- Proprietary differential input that maintains excellent SNR performance for input frequencies up to 300 MHz.
- Operation from a single 1.8 V supply and a separate digital output driver supply accommodating 1.8 V CMOS or LVDS outputs.
- Standard serial port interface (SPI) that supports various product features and functions, such as data formatting (offset binary, twos complement, or gray coding), enabling the clock DCS, power-down, test modes, and voltage reference mode.
- Pin compatibility with the AD9268, allowing a simple migration from 14 bits to 16 bits. The AD9258 is also pin compatible with the AD9251, AD9231, and AD9204 family of products for lower sample rate, low power applications.

Product Detail
This page contains evaluation board documentation and ordering information for evaluating the AD9258.
The AD9258-80EBZ is an evaluation board for the AD9258, dual 14-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 AD9258.
The AD9258 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.
