Description
AI
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.PRODUCT HIGHLIGHTSIntegrated 8-bit, 500 MSPS ADC.Single 1.8 V supply operation with LVDS outputs.Power-down option controlled via a pin-programmable setting.APPLICATIONSBattery-powered instrumentsHandheld scope metersLow cost digital oscilloscopesOTS: video over fiber
