AD9286 - 1.8 V Dual Analog-to-Digital Converter

General Description

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.
