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 ponents are required for many applications. The digital outputs are LVDS patible. 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. PRODUCT HIGHLIGHTS 1. Integrated 8-Bit, 500 MSPS ADC. 2.
