The AD9286 is an 8-bit, monolithic sampling, analog-to-digital converter (ADC) that supports interleaved operation and is optimized for low cost, low power, and ease of use. Each ADC operates at up to a 250 MSPS conversion rate with outstanding dynamic performance.
The AD9286 takes a single sample clock and, with an on-chip clock divider, time interleaves the two ADC cores (each running at one-half the clock frequency) to achieve the rated 500 MSPS. By using the SPI, the user can accurately adjust the timing of the sampling edge per ADC to minimize the image spur energy.
The ADC requires a single 1.8 V supply and an encode clock for full performance operation. No external reference components are required for many applications. The digital outputs are LVDS compatible.
The AD9286 is available in a Pb-free, 48-lead LFCSP that is specified over the industrial temperature range of −40°C to +85°C.

Evaluation Kits (1)
The AD9286-500EBZ is an evaluation board for the AD9286, 8-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 AD9286.
The AD9286 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 firstname.lastname@example.org
